ABSTRACT:
Allylic 1-hydroxy alcohols are inverted to allylic 3-hydroxy alcohols by: (1) epoxidizing the allyl group of the allylic 1-hydroxy alcohol to the corresponding 2,3-epoxy-1-hydroxy alcohol; (2) transforming the 2,3-epoxy-1-hydroxy alcohol compound to a 1,2-dihalo-3-hydroxy alcohol; and (3) dehalogenating the 1,2-dihalo-3-hydroxy alcohol to form the desired allylic 3-hydroxy alcohol.
