A convenient and efficient synthesis of 1,2-azido alcohols has been achieved by regioselective ring opening of epoxides using NaN3 and 4 Å molecular sieves in acetonitrile. The utility of this method has been demonstrated by achieving a short synthesis of (−)-cytoxazone in 48% overall yield.
通过使用乙腈中的NaN 3和4Å分子筛对环氧化物进行区域选择性开环,已实现了一种便捷高效的1,2叠氮基醇的合成。通过以48%的总收率实现(-)-cytoxazone的短时合成,已证明了该方法的实用性。
