Novel and practical acid-catalyzed cyclization of 2-indolyl aryl carbinols via tandem dehydration/1,5-hydride shift/7-cyclization sequences has been developed. By appropriate variation of the substrate, diverse polycyclic-fused indoles were synthesized in good yield, thus demonstrating the high efficiency, transition-metal-free nature, and high step/atom economy of the synthesis strategy.
已经开发了通过串联脱水/ 1,5-氢化物转移/ 7-环化序列的新颖且实用的酸催化2-吲哚基芳基甲醇的环化反应。通过适当地改变底物,以高收率合成了各种多环稠合的吲哚,从而证明了合成策略的高效率,无过渡金属的性质和高步骤/原子经济性。
