摘要
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 alpha -amino-esters. This paper reports the optimization, scope and stereoselectivity of this reaction to give octahydroindoles (2-azabicyclo[4.3.0]nonanes).
