Total synthesis of ceratopicanol (1) was achieved with a tandem cycloaddition reaction of allenyl diazo compound 6 via a trimethylenemethane (TMM) diyl intermediate. The TMM diyl mediated [2+3] cycloaddition reaction furnished the consecutive quaternary carbon centers and showed an unusual diastereoselectivity.
烯丙基重氮化合物6经由三亚甲基甲烷(TMM)二芳基中间体的串联环加成反应可实现Ceratopicanol(1)的全合成。TMM二基介导的[2 + 3]环加成反应提供了连续的季碳中心,并显示出不同寻常的非对映选择性。
