  Kinetic enzymatic resolution of β-tetralols

  摘要：

  Several substituted beta-tetralols 1a-e and beta-tetralol 2 were successfully resolved using porcine pancreatin in hydrocarbon solvents. All attempts to resolve the substituted beta-tetralols by diasteromeric derivatization have failed. The absolute configuration of the products was established by literature precedence.

  Synthesis and structure-activity relationships of naphthalene-substituted derivatives of the allylamine antimycotic terbinafine

  摘要：

  Derivatives of the allylamine antimycotic terbinafine (1) with varied substitution at the naphthalene ring system have been prepared, and their antifungal activity has been evaluated. In general, the potency is strongly dependent on the bulkiness of the substituent. Only hydrogen or in some cases fluorine are tolerated as substituents at positions 2-4 and 6-8 of the naphthalene moiety, whereas 5-substituents may be larger in size (F, Cl, Br, Me). Derivatives with fluorine at positions 3, 5, and 7 or chlorine at position 5 showed enhanced activity against yeasts relative to 1. This increase in sensitivity could be intensified by simultaneous introduction of two fluoro substituents at positions 5 and 7. Compound 7q demonstrated 8-to 16-fold improved potency against Aspergillus fumigatus, Candida albicans, and Candida parapsilosis.
