Abstract
The thermolysis of the beta-lactam-based oxazolidinone 1 leads to the formation of cycloadducts 2 and evidence is presented for the particip ation of the carboxylated azomethine ylide 4, rather than 3 (the more conventional product of oxazolidinone fragmentation), as the key 1,3-d ipolar intermediate in this process.
