The stereochemistry of the nitroolefins 1 prepared by known methods was unambigously established.Their reactions with azomethine ylides (e.g. 8) was studied and the stereochemistry of the adducts as well.This preliminary work was necessary to substantiate a discussion of structural (pyrrolidines conformational analysis) and mechanistic problems (dipolarophile-azomethine ylide approach and HNO2 elimination from the nitro pyrrolidines).
