T. Itoh et al., EFFICIENT SYNTHESIS OF ENANTIOPURE 1,2-BIS(HYDROXYMETHYL)-3,3-DIFLUOROCYCLOPROPANE DERIVATIVES THROUGH LIPASE-CATALYZED REACTION, Chemistry Letters, (9), 1998, pp. 903-904
Efficient synthesis of chiral difluorocyclopropane building block has
been accomplished; prochiral diacetate of 1,2-bis(hydroxymethyl)-3, 3-
difluorocyclopropane was converted to the corresponding monoacetate th
rough Alcaligenes sp. lipase-catalyzed hydrolysis with >99% enantiomer
ic excess.
