synthesis of ergosta-5,7,22,24(28)-tetraen-3β-ol. An analogous synthesis of ergosta-5,7,22,24(28)-tetraen-3β-ol using radioactive intermediates enabled the intermediacy of this compound in ergosterol biosynthesis in yeast to be demonstrated.
麦角固醇与4-苯基-1,2,4-三唑啉-3,5-二酮之间的狄尔斯-阿尔德加合物通过氢化铝锂还原,可高产率地转化为麦角固醇。该加合物已用于合成麦角甾醇-5,7,22,24(28)-丁烯-3β-ol。使用放射性中间体类似地合成麦角甾醇-5,7,22,24(28)-丁烯-3β-ol使得该化合物在酵母麦角固醇生物合成中具有中介作用。
