The aldehyde 2-formyl-2-(pent-4-enyl)-1,3-dithiane 1, containing both alkene and aldehyde functional groups, is a good substrate for intramolecular dipolar cycloaddition reactions after condensation with various N-alkyl α-amino-esters. This paper reports the optimization, scope and stereoselectivity of this reaction to give octahydroindoles (2-azabicyclo[4.3.0]nonanes).
醛 2-甲酰基-2-(戊-4-烯基)-1,3-二噻烷 1 同时含有烯和醛官能团,是与各种 N-烷基 α-氨基酯缩合后进行分子内双极环加成反应的良好底物。本文报告了这一反应的优化、范围和立体选择性,从而得到八氢吲哚(2-氮杂双环[4.3.0]壬烷)。
