Title:
METHODS FOR MAKING 3-O-PROTECTED MORPHINONES AND 3-O-PROTECTED MORPHINONE DIENOL CARBOXYLATES
Document Type and Number:
WIPO Patent Application WO2005077957
Kind Code:
A3
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 R1SR2 and a base. In one embodiment, the alcohol is a compound of formula (I) wherein R3 is 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.
