unprecedented gold-catalyzed [2+2+2+2]-annulation of 1,3,5-hexahydro-1,3,5-triazines with alkoxyallenes has been developed, providing eight-membered heterocycles in good to excellent yields. Deuterium labeling and control experiments reveal the possible reaction mechanism for this annulation.
已经开发了前所未有的金催化的1,3,5-六氢-1,3,5-三嗪与烷氧基丙烯烯的[2 + 2 + 2 + 2]环化反应,提供了八元杂环,收率好至极佳。氘标记和对照实验揭示了这种环空反应的可能反应机理。
