GRAPHICSA truly general, versatile, and highly regio- and stereoselective methodology for the synthesis of terpenoids containing 1,5-diene units of E and/or Z geometry critically involves Pd-catalyzed homoallyl- and homopropargyl-alkenyl coupling and Zr-catalyzed carboalumination of alkynes. By using this methodology, coenzyme Q(10), (E,Z,E)-geranylgeranoll, and other natural or unnatural compounds have been synthesized efficiently.

A stereocontrolled synthetic route has been used to prepare two of the geometric isomers of all-trans-GGPP. Neither of these isomers is effective substrates for mammalian GGTase I, but 3 is a potent inhibitor of this enzyme (IC50 = 100 nM). Surprisingly, both compounds are effective substrates for mammalian FTase. (C) 2001 Elsevier Science Ltd. All rights reserved.
