详细

Attempts to replace the allylic C15-acetate group of cloprostenol with a tosyl group under phase-transfer catalysis conditions (СH2Cl2/H2O, R3R′N+Hal-, NaOH, TsOH, Pd(PPh3)4) led to the corresponding 13E, 15Z derivative with moderate yield. The same compound is stereoselectivity formed in high yield when this reaction is carried out in a THF-Pd(PPh3)4-NaH medium.
