✦ Synopsis


25-and 26-monofluorophytosterols were synthesized from stigmasterol as potential arthropod-activated competitive inhibitors of side chain hydroxylations occurring in ecdysone biogenesis. An attractive biosynthetic pathway for the design of arthropod-selective control agents is the conversion of dietary C28 and C2g sterols via cholesterol to the ecdysteroid molting hormones. This requires dealkylation at C-24, several oxidative steps in the sterol nucleus, and finally hydroxylation at C-20,
