A Simple Procedure for Selective Acylation of the Less Reactive Hydroxyl Functionality in Some Dihydroxylated Compounds

Abstract
Phenolic (3′) esters (acetate, N-t-Boc glycinate) of the (+) 3S, 4S 5′(1′,1′-dimethylheptyl)-7-hydroxy-δ6−tetrahydrocannabinol (dexanabinol) were synthesized via the 7′-trifluoroacetate followed by acylation and subsequent deprotection.
