been synthesized by a facile route starting from 4-pentyn-1-ol. The enantioselectivity was attained by a strategy involving a lipase-catalyzedacetylation of a solid-phase immobilized long chain α-hydroxyacid. Another important feature of the synthesis was the formulation of an efficient HgO-catalyzed O-methylation of the α-hydroxyacids which proceeded without any racemization. The alkylation protocol
