该中间体在本合成路线中的序号:(LXX)17) Pandey et al. reported an efficient synthesis of epibatidine via [3+2] cycloaddition of nonstabilized azomethine ylide and substituted 6-chloro-3-vinylpyridine. The precursor (LXX) was obtained in 73% yield from N-BOC pyrrolidine (LXIX) by standard manipulations. The [3+2] cycloaddition between (LXX) and alpha,beta-unsaturated ester (LXXI) furnished cycloadduct (LXXII) stereoselectively. Decarboxylation followed by reductive N-debenzylation converted (LXXII) into (I) in 78% overall yield.
