A Novel Synthesis of 9,13-dicis Double Bonds Locked Retinoids
摘要:
Synthesis of two retinoids in which the 9,13-dicis double bonds were locked in cycloalkene or thiophene was described. The key step was carbonylation of vinyl bromide 9 and 16 with carbon monoxide in the presence of Pd(PPh3)(4). (C) 1997 Elsevier Science Ltd.
