Abstract
Cholest-2-on-6-one, 3, is an important synthetic intermediate in the preparation of ecdysone and related insect moulting hormones.1–3 We report here a convenient two-step synthesis of this compound from cholesterol which combines in one step the elimination of a 36 borate ester and hydroboration-oxidation at C-6.
