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.
已经确定三氟甲磺酸铋(III)在温和的反应条件下催化γ-烯丙基酮的环化反应。该反应允许从环状酮衍生物中选择性地形成多环叔醇。所得的二烯醇可以进行立体选择性环加成反应,有效地提供复杂的多环体系。
