ABSTRACT:
Disclosed are methods for making aldehydes and ketones comprising allowing the corresponding primary or secondary alcohol to react in the presence of trichoroisocyanuric acid, a compound of formula R1SR2and a base. In one embodiment, the alcohol is a compound of formula (I):wherein R3is a protecting group.Also disclosed are methods for making 3-O-protected morphine dienol carboxylates comprising allowing a compound of formula (I) to oxidize in the presence of a chlorine-containing compound and a compound of formula R1SR2; and allowing the product of the oxidation step to react with an acylating agent.
