Synthesis of substituted pyrrolidines by reaction of aryl-substituted vinylidenecyclopropanes with aromatic imines catalyzed by BF3·Et2O
摘要:
The reactions of 1,1-diaryl-2-(diphenylvinylidene)cyclopropanes and 1,1-diaryl-2-(2-phenylpropenylidine) cyclopropanes with aromatic amines in the presence of BF3 center dot Et2O leads to the formation of pyrrolidine derivatives.
