An efficient synthesis of o-terphenyls from Morita–Baylis–Hillman adducts of cinnamaldehydes: a consecutive bromination, Wittig reaction, 6π-electrocyclization, and an aerobic oxidation process
摘要:
An efficient synthetic method of o-terphenyls was developed from Morita-Baylis-Hillman adducts. The synthesis was carried out via a sequential bromination of MBH adducts, Wittig reaction with various aldehydes, 6 pi-electrocyclization, and a base-mediated aerobic oxidation process.
