摘要
A potentially general route to the 1-azabicyclo]n,m.O[alkane skeleton of various alkaloids is embodied in the intramolecular 1,3-dipolar cycloaddition of aliphatic azides with omega-chloroalkenes. Cycloaddition is followed by rearrangement and intramolecular N-alkylation, affording bicyclic iminium ions 1 in one operation. The application of this method to the synthesis of (+/-)-sigma-coniceine 6, (1S,2R,8aR)-indolizidine-1,2-diol 13 and (-)-swainsonine 15 is described.
