A facile microwave assisted synthesis and antimicrobial activities of naturally occurring (E)-cinnamyl (E)-cinnamates and (E)-aryl cinnamates

摘要

Benzaldehydes la-e on reaction with phosphorane 3 and aldehydes 2a-e with phosphorane 4 under microwave irradiation provide the (E)-cinnamyt (E)-cinnamates 5a-e and (E)-aryl cinnamates 6a-e respectively in high yield. Cinnamates 5a-e and 6a-e exhibit antibacterial and antifungal activity.
