Bio-olefins via condensation metathesis chemistry

Amino acid based polymers are of interest for a variety of biomaterial applications including drug delivery, proteomics, and tissue engineering. A new class of polymers bearing amino acids and dipeptides has been prepared using acyclic diene metathesis (ADMET) to create copolymers of polyethylene with linear amino alcohol, branched amino acid, or branched peptide substituents termed bio-olefins. Monomers with the amino acid/dipeptide functionality attached through both the N and C-terminus have been prepared, and a discussion on the synthesis of the monomers and a comparison of the thermal properties of the resulting polymers are discussed. The resulting highly functionalized polymers are strong, film-forming materials with moduli in the range of LDPE with molecular weights typical of polycondensation polymers, i.e. Nylon and PET.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 246047-72-3 is helpful to your research., Application of 246047-72-3

Application of Ru(II)-Catalyzed Enyne Cyclization in the Synthesis of Brefeldin A

The approach to brefeldin A described herein hinges on Ru(II)-catalyzed cycloisomerization of an enyne obtained by the reaction of an alkynylzinc reagent with an alpha-chloro sulfide. Other key steps include Mislow-Evans rearrangement, cross-metathesis, and macrocyclization using a Roush-Masamune protocol.

PROCESS FOR CO-PRODUCING OLEFINS AND DIESTERS OR DIACIDS STARTING FROM UNSATURATED FATS

In order to produce both an olefinic fraction and a composition of diacids or diesters of fats, a process is carried out which comprises, in succession: a) metathesis of an unsaturated fat with ethylene in the presence of at least one non-aqueous ionic liquid; b) separating and recycling the ionic liquid used in the first step; c) separating, by distillation, the olefinic fraction (fraction A) from the unsaturated fat mono-ester or mono-basic acid fraction (fraction B) formed in step a); d) homometathesis of the mono-unsaturated fat ester or acid cut (fraction B) which allows the co-production of unsaturated fat diesters or diacids (fraction C) and ethylene which is recycled to the first methathesis step of the process; and e) optionally, recycling the ionic liquid containing the catalyst used in step d). Of particular application to an oleic sunflower oil, an oleic rapeseed oil or to a mixture of mono-alcohol esters of said oils, whereupon the process can produce both an olefinic fraction (mainly composed of 1-decene) and a composition of diesters or diacids wherein, in general, over half of the chains is constituted by unsaturated C18 chains (mainly composed of octadecene-9 1,18-diacid or diester) and to recycle the ethylene employed.

Regioselective Chromatic Orthogonality with Light-Activated Metathesis Catalysts

The ability to selectively guide consecutive chemical processes towards a preferred pathway by using light of different frequencies is an appealing concept. Herein we describe the coupling of two photochemical reactions, one the photoisomerization and consequent activation of a sulfur-chelated latent olefin-metathesis catalyst at 350nm, and the other the photocleavage of a silyl protecting group at 254nm. Depending on the steric stress exerted by a photoremovable neighboring chemical substituent, we demonstrate the selective formation of either five- or six-membered-ring frameworks by light-triggered ring-closing metathesis. The orthogonality of these light-induced reactions allows the initiation of these processes independently and in interchangeable order, according to the wavelength of light used to promote them. A guiding light: By the combination of a light-activated sulfur-chelated olefin-metathesis catalyst with a photocleavable bulky silyl protecting group, two orthogonal pathways enabled the selective synthesis of five- or six-membered heterocycles according to the order in which the starting material was irradiated with light of different wavelengths. Thus, protecting-group removal and metathesis gave either a dihydropyran or a dihydrofuran.

Synthesis and conformational analysis of cyclic analogues of inverse gamma-turns

gamma-Turn analogues comprising a modified dipeptide constrained in an eleven-membered ring were prepared by alkene metathesis and analysed by NMR and molecular modelling studies. The results reveal that some of the cyclic analogues form inverse gamma-turns and preferentially adopt conformations determined by the identity of the incorporated amino acid residues and the nature of the constraining linker (E/Z-alkene or alkane).

Design, chemical synthesis, and in vitro biological evaluation of simplified estradiol-adenosine hybrids as inhibitors of 17beta-hydroxysteroid dehydrogenase type 1

A series of estradiol (E2) derivatives were designed to interact with, both the substrate- and the cofactor-binding sites of 17beta-hydroxysteroid dehydrogenase type 1 (17beta-HSD1). These analogues of potent E2-adenosine hybrid inhibitor EM-1745, where the adenosine moiety was replaced by a more stable benzene derivative, were synthesized from estrone using alkene cross-metathesis and Sonogashira coupling reactions as key steps. In vitro biological evaluation of these steroid derivatives revealed that a spacer of 13 methylenes, between the 16beta-position of E2 and the adenosine mimic bearing a carboxylic acid, group, gave the best inhibition of 17beta-HSD1.

An eco-compatible strategy for the diversity-oriented synthesis of macrocycles exploiting carbohydrate-derived building blocks

An efficient, eco-compatible diversity-oriented synthesis (DOS) approach for the generation of library of sugar embedded macrocyclic compounds with various ring size containing 1,2,3-triazole has been developed. This concise strategy involves the iterative use of readily available sugar-derived alkyne/azide-alkene building blocks coupled through copper catalyzed azide-alkyne cycloaddition (CuAAC) reaction followed by pairing of the linear cyclo-adduct using greener reaction conditions. The eco-compatibility, mild reaction conditions, greener solvents, easy purification and avoidance of hazards and toxic solvents are advantages of this protocol to access this important structural class. The diversity of the macrocycles synthesized (in total we have synthesized 13 macrocycles) using a set of standard reaction protocols demonstrate the potential of the new eco-compatible approach for the macrocyclic library generation.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 246047-72-3 is helpful to your research., Application of 246047-72-3
