It has been established that bismuth(III) triflate catalyzes the cyclization of γ‐allenic ketones under mild reaction conditions. This reaction allows the selective formation of polycyclic tertiary alcohols from cyclic ketone derivatives. The resulting dienols can engage in stereoselective cycloadditions to efficiently afford complex polycyclic systems.
现已确定,在温和的反应条件下,三氟甲磺酸铋(III)可以催化γ-烯烃酮的环化反应。该反应允许由环酮衍生物选择性地形成多环叔醇。所得二烯醇可以参与立体选择性环加成反应,以有效地提供复杂的多环系统。
