Reductive alkylation of anhydrides and lactones: Direct access to monosubstituted lactones

Reductive alkylation of anhydrides (1 equiv) with a 2:0.25 mixture of Grignard reagent and Zn(BH4)2 afforded monosubstituted lactones in moderate yields. The same sequence applied to unsubstituted lactones gave monoalkylated diols, which were further selectively oxidised with tetra-n-propylammonium perruthenate (TPAP) into the expected monoalkylated lactones.

Selectivity Modulation of the Ley?Griffith TPAP Oxidation with N-Oxide Salts

A wide variety of novel non-hygroscopic N-oxide tetraphenylborate salts were synthesized and evaluated as co-oxidants in the Ley?Griffith (TPAP) oxidation of benzylic and allylic alcohols under non-anhydrous conditions. The novel DABCOO¡¤TPB (2:1) salt was herein unearthed as a viable competitor to the first-generation NMO¡¤TPB (2:1) salt, but more importantly gave increased performance under oxidative competition. X-ray crystal structure analysis and NMR spectroscopy revealed that depending on the crystallization conditions 1:1, 2:1 or 3:2 N-oxide?tetraphenylborate salts could be formed.

A preliminary investigation on the use of organic ionic liquids as green solvents for acylation and oxidation reactions

Different organic ionic liquids (OILs) have been used as green solvents in Friedel-Crafts acylation and alcohol oxidation reactions. Specifically, three OILs were employed, 1-ethyl-3-methylimidazolium chloride, tetraethylammonium bromide, and 1-butyl-3-methylimidazolium chloride, and four reactions studied, acylation of toluene by acetyl chloride, acylation of benzene by propionyl chloride, oxidation of benzyl alcohol by N-methylmorpholine N-oxide, and oxidation of salicylic alcohol by o-iodoxybenzoic acid. The reactions were carried out, at room temperature, in a well-stirred lab-scale glass batch reactor, under inert atmosphere and for reaction times ranging from 5 to 90 min. Gas chromatography was employed to characterize the reaction products. First of all, the desired products yield as a function of the reaction time was investigated. Moreover, simple kinetic models were built for the interpretation of the experimental results. Additional tests were carried out to assess the possibility of recycling the OILs employed. The results of this preliminary study were satisfactory as the OILs investigated proved to be good media in which to carry out the reactions studied in this work (desired products yield greater than 90% were achieved). Moreover, the reaction rate expressions of the kinetic models were able to satisfactorily predict the experimental results. Finally, the possibility of recycling the OIL (in one of the reactions) was proved to be feasible and this suggests the use of recycled OIL together with a fresh make-up, to match high yield values with economical/ecological advantages.

Optical properties of synthetic porphyrins bearing or lacking an exo-five-membered ring and a keto carbonyl group on it, both of which are present in naturally occurring chlorophylls

By modifying beta-octaethylporphyrin we prepared 131-oxo- and deoxo-porphyrins 1 and 3 possessing an exo-five-membered E-ring, which is a structural requirement of naturally occurring chlorophyllous pigments, and also 131-oxo- and deoxo-porphyrins 2 and 4 lacking the E-ring as reference compounds. Visible absorption spectra of 131-deoxo-porphyrins 3/4 bearing/lacking the E-ring and their zinc complexes showed a relatively small difference, indicating that geometry of the tetrapyrrole unit in 3 was altered by formation of the E-ring but its contribution to the visible spectrum was limited. In contrast, a spectral difference between 131-oxo-porphyrins 1/2 bearing/lacking the E-ring (as well as their zinc complexes) was clearly observed; fixation of 131-oxo group by the E-ring as in 1 resulted in its red-shifted absorption spectrum (ca. 10 nm for each band). These results indicated that introduction of the E-ring to a porphyrin macrocycle slightly affected its optical properties and that a larger effect was observed by fixation of 131-oxo group to a porphyrin pi-conjugate system.

Applications of fluorine-containing amino acids for drug design

Fluorine-containing amino acids are becoming increasingly prominent in new drugs due to two general trends in the modern pharmaceutical industry. Firstly, the growing acceptance of peptides and modified peptides as drugs; and secondly, fluorine editing has become a prevalent protocol in drug-candidate optimization. Accordingly, fluorine-containing amino acids represent one of the more promising and rapidly developing areas of research in organic, bio-organic and medicinal chemistry. The goal of this Review article is to highlight the current state-of-the-art in this area by profiling 42 selected compounds that combine fluorine and amino acid structural elements. The compounds under discussion represent pharmaceutical drugs currently on the market, or in clinical trials as well as examples of drug-candidates that although withdrawn from development had a significant impact on the progress of medicinal chemistry and/or provided a deeper understanding of the nature and mechanism of biological action. For each compound, we present features of biological activity, a brief history of the design principles and the development of the synthetic approach, focusing on the source of tailor-made amino acid structures and fluorination methods. General aspects of the medicinal chemistry of fluorine-containing amino acids and synthetic methodology are briefly discussed.

Synthesis of 3-spiromorpholinone androsterone derivatives as inhibitors of 17beta-hydroxysteroid dehydrogenase type 3

Spiromorpholinone derivatives were synthesized from androsterone or cyclohexanone in 6 or 3 steps, respectively, and these scaffolds were used for the introduction of a hydrophobic group via a nucleophilic substitution. Non-steroidal spiromorpholinones are not active as inhibitors of 17beta-hydroxysteroid dehydrogenase type 3 (17beta-HSD3), but steroidal morpholinones are very potent inhibitors. In fact, those with (S) stereochemistry are more active than their (R) homologues, whereas N-benzylated compounds are more active than their non substituted precursors. The target compounds exhibited strong inhibition of 17beta-HSD3 in rat testis homogenate (87-92% inhibition at 1 muM).
