Abstract

Process for the preparation of a taxol intermediate comprising contacting an alcohol with an oxazinone having the formula:

(see formula 1) wherein R1 is aryl, heteroaryl, alkyl, alkenyl, alkynyl or OR7 wherein R7 is alkyl, alkenyl, alkynyl, aryl or heteroaryl; R2 and R5 are independently selected from hydrogen, alkyl alkenyl, alkynyl, aryl, heteroaryl, and OR8 wherein R8 is alkyl, alkenyl, alkynyl, aryl, heteroaryl, or hydroxyl protecting group; and R3 and R6 are independently selected from hydrogen, alkyl, alkenyl, alkynyl, aryl and heteroaryl.
