LIPASE－CATAL YZED DOUBLE KINETIC RESOLUTION OF DL－2，4－DIMETHYL－1，5－PENTANEDIOL：A USEFUL SYNTHON IN NATURAL PRODUCT SYNTHESIS

An importment chiral synthon (-)-2,4-dimethyl-1,5-pentanediol and its diester and monoester were obtained by lipase-catalyzed double kinetic resolution.

Chemo-Enzymic Synthesis of a Four-Chiral-Center Portion of A-23187(Calcimycin)

A four-chiral-center portion of A-23187 was synthesized from a chiral synthon which was obtained from lipase-catalyzed resolution.
