| 2 | Synthesis of 24-Methylene-cholest-5-ene-7-oxo-3β,19-diacetate显示文摘24-Methylenecholest-5-ene-7-oxo-3β,19-diacetate 5 was synthesized starting from stigmasterol via twelve step reactions in 4.1% overall yield. It can be served as a key intermediate for the synthesis of 24-methylenecholest-5-ene-3β,7β,19-triol 1, a naturally occuring polyhydroxylated sterol with potential biological activity. | WeiGangLU CuiXianZHANG JingYuSU LongMeiZENG | 2005 | Chinese Chemical Letters2005，16，5： | 0 |
