generality of this anionic polar cycloaddition with activated triple bonds, we have now found that reaction of ( 2) with phenylpropiolic acid N, N-dimethylamide (3) affords 2,4,5-triphenyl-3-pyrroline-3-carboxylic acid N,N-dimethylamide ( 4 4 , thus indicating that electron-withdrawing groups are no
