  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.

  通过可调节的瞬时配体策略克服 1-萘醛 C-H 甲基化的邻位和邻位选择性

  摘要：

  甲基广泛存在于生物活性分子中，位点特异性甲基化已成为其结构功能化的重要策略。为了引入这种最小的烷基手柄，我们开发了一种通过使用瞬时配体策略对 1-萘醛进行高度区域选择性的邻位和邻位-C–H 甲基化的方法。一系列甲基取代的萘骨架已以中等至优异的产率制备。机理研究表明，邻甲基化是由1-萘醛邻位较高的电子密度以及中间5,6-稠合双环钯环的形成控制的，而实验研究和理论计算推断，5元环1-萘醛邻位的铱环通过周围环和邻环之间的相互转化导致能量上有利的邻甲基化。重要的是，为了证明该方法的合成效用，我们证明该策略可以作为合成多取代萘基生物活性分子和天然产物的平台。

• An analysis of the complementary stereoselective alkylations of imidazolidinone derivatives toward α-quaternary proline-based amino amides

  Alkylations of praline-based imidazolidinones are described based on the principle of self-regeneration of stereocenters (SRS), affording high levels of either the cis or trans configured products. Stereoselectivity is dictated solely on the nature of the 'temporary' group, where isobutyraldehyde-derived imidazolidinones provide the cis configured products and 1-naphthaldehyde-derived imidazolidinones afford the complementary trans configured products. These stereodivergent products can be readily cleaved to afford both alpha-alkylated proline enantiomers from readily available L-proline. A series of imidazolidinones were alkylated to investigate the origin of the anti-selectivity. Potential contributions toward the observed anti-selectivity are discussed on the basis of these experiments, suggesting a refined hypothesis for selectivity may be in order. (C) 2015 Elsevier Ltd.
