A palladium-catalyzed dicarbonylation ofp-benzoquinones with aryl triflates has been developed. Using Cr(CO)6as the CO source, the reaction proceeds smoothly and efficiently to give a series of aryl esters in moderate to good yields (up to 90%).

(Chemical Equation Presented) With use of inexpensive commercially available raw materials, chromanmethanol precursors to the natural β-, γ-, and δ-tocotrienols have been prepared in high yield. Enzymatic resolution afforded chiral chromanmethanols in high enantiomeric excess. Subsequent attachment of the farnesyl side chain was high yielding, thus allowing the preparation of asymmetric β-, γ-, and δ-tocotrienols in one final step wherein simultaneous deprotection of the phenol and removal of the sulfone group occurs. This chemistry provides the first synthesis of natural-series β-tocotrienol.
