Chemoselectivity of the reactions of diazomethanes with 5-benzylidene-3-phenylrhodanine
The reactions of 5-benzylidene-3-phenylrhodanine (2; rhodanine = 2-thioxo-1,3-thiazolidin-4-one) with diazomethane (7a) and phenyldiazomethane (7b) occurred chemoselectively at the exocyclic C=C bond to give the spirocyclopropane derivatives 9 and, in the
