An useful A-ring building block for the total synthesis of vitamin D-3 cong
eners, compound 7, has been prepared starting from vitamin D-2 by a chemo-e
nzymatic approach that relies on lipase-catalyzed acylation in an organic s
olvent for the stereoselective step. (C) 2000 Elsevier Science Ltd. All rig
