aldehydes containing allene side chains is a versatile reaction as it provides a rapid and efficient access to original complex structures such as 1,3,4-tetrahydro-1,4-epoxy-5-alkylidene-2-benzoxepines 2 and substituted 2-oxa-tricyclo[5.2.2.0] (1,5)undeca-4,8,10-triene-9-carbaldehydes 3. Novel polycyclic structures are characterized, and optimized strategies for the synthesis of the substrates 1 are
含有烯丙基侧链的芳基醛的分子内光环加成反应是一种多用途反应,因为它可以快速有效地访问原始的复杂结构,例如1,3,4-四氢-1,4-环氧-5-亚烷基-2-苯并庚二酮2和取代的2-oxa-tricyclo [5.2.2.0](1,5)undeca-4,8,10-triene-9-carbaldehydes 3.表征了新型多环结构,并描述了合成底物1的优化策略。
