IMPROVED SYNTHESIS OF 1,2,4-TRIAZOLINE-3,5-DIONE DERIVATIVES OF ERGOSTEROL AND A NEW METHOD FOR THEIR RECONVERSION TO ERGOSTEROL

The ergosterol diene system reacts in excellent yield with a series of 4-substituted 1,2,4-triazoline-3,5-diones generated by in situ oxidation of the appropriate hydrazides with phenylseleninic anhydride or phenylseleninic acid.Diaryltelluroxide and diphenylselenoxide are also efficient oxidants.The diene system can be smoothly regenerated by alkaline hydrolysis.
