✦ Synopsis

A Convenient Method for Retro-Cycloaddition of Adducts from Steroidal 5,7-Dienes and 4-Phenyl-1,2,4-triazolidine-3,5-dione and Application to the Syntheses of Biosynthetic Intermediates of Ergosterol.

-A novel method for the deprotection to the 5,7-diene system in steroids is developed which is also useful in ergosterol derivatives such as (IIe).
