Synthesis and structure-activity relationships of benzo[b]thienylallylamine antimycotics
摘要:
Benzo[b]thiophene analouges of the allylamine antimycotic terbinafine (2) bearing the side chain at various positions and optionally substituted by halogen have been prepared and their antifungal activity studied. Derivatives bearing the side chain at positions 3, 4, or 7 are bioequivalents of 2. Compounds containing the allylamine side chain at position 7, with a further substituent at position 3, showed significantly enhanced activity against Candida albicans, an effect which appears to be specifically linked only to this particular substitution pattern. 3-Chloro-7-benzo[b]thienyl derivative 7m was found to be the most potent allylamine antimycotic identified so far. In general, substituted benzo[b]thiophenes can be used not only as potential equivalents of naphthalene in bioactive compounds but also as a tool to selectively modify biological activities.
A facile and efficient protocol for the α-benzoyloxylation of β-keto sulfides is presented. This methodology provides a step-economical, mild and practical access to highly functionalized α-O-benzoyloxy substituted β-keto sulfides, including those with quaternary carbons, which are not easily obtained through currently available methods.

pathway to α-sulfenylated carbonyl compounds from commercially available thiols and universally employed TEMPO and its analogues, which act as C3 synthons through skeletal rearrangement under simple and metal-free conditions. Mechanism studies suggest that this reaction involves a consecutive radical oxidation and cation coupling process. TEMPO analogues and thiols serve as oxidants and reductive reagents
