Enzymatic preparation of homochiral 2-(n-carbobenzyloxypiperid-4-yl)-1,3-propanediol monoacetate. A facile entry to both enantiomers of 3- hydroxymethylquinuclidine.
摘要:
Both enantiomers of monoacetate 1 have been prepared in high ee by lipase catalyzed monohydrolysis of the prochiral diacetate 3 and by monoacetylation of the corresponding diol 4. 3-Hydroxymethylquinuclidine 2 was then synthesized in both enantiomeric forms with an ee up to 98% starting from (+)-1.
