Chemoenzymatic synthesis of 1α,24(R)-dihydroxycholesterol
摘要:
1 alpha,24(R)-Dihydroxycholesterol, which is the key intermediate for the synthesis of 1 alpha,24(R)-dihydroxyvitamin D-3, was effectively synthesized via stereoselective esterification of the 24(R)-hydroxy group using a lipase in combination with inversion of configuration of the 24(S)-hydroxy group using the Mitsunobu reaction (R:S=99:1).
