Synthesis of 1,5-dihydro-2H-pyrrol-2-ones from an alkyne, an imine and carbon dioxide via an organotitanium intermediate
摘要:
Azatitanacyclopentene complexes 2 react with carbon dioxide under atmospheric pressure to afford 1,5-dihydro-2H-pyrrol-2-ones, thus providing a one-pot procedure for synthesizing a variety of 1,5-dihydro-2H-pyrrol-2-ones from an alkyne, an imine and carbon dioxide under mild conditions.
