A new sequence of autocatalysis–catalysis in asymmetricalkynylation of azaarylaldehydes in the presence of Soai (5-pyrimidyl)alkanol as chiral catalyst is documented. The autocatalyst can be generated from almost racemic environment to up to 99.5 % ee and subsequently propagates this chirality to provide propargylic alcohols in up to 86 % ee.
记录了在 Soai (5-嘧啶基) 烷醇作为手性催化剂存在下,氮杂芳基醛的不对称炔基化的自催化新序列。自动催化剂可以从几乎外消旋的环境中产生,最高可达 99.5% ee,随后扩展这种手性以提供最高 86% ee 的炔丙醇。
