The reaction of 1-substituted vinamidinium sails with sarcosine ethyl ester produced 2,3-disubstituted pyrroles; a similar reaction with glycine ethyl ester gave 2,5-disubstituted pyrroles. Reactions of related thr~--carbon synthons with sarcosinΒ’ and glycine were studied under basic, neutral and ac
