Synthesis of alkyl-1,3-dihydro-3-oxobenzo[c]oxepine-4-carboxylates
摘要:
Alkyl-1,3-dihydro-3-oxobenzo[c]oxepine-4-carboxylates were obtained by bromination of dialkyl-2-(2-methylbenzylidene)malonates with N-bromosuccinimide followed by the cyclization of dialkyl-2-(2-bromomethylbenzylidene) malonates.
