ENZYME-MEDIATED ASYMMETRIC HYDROLYSIS OF α-BENZYLOXYCARBOXYLIC ESTERS
Kato, Yasuo,Ohta, Hiromichi,Tsuchihashi, Gen-ichi
, p. 1303 - 1306 (2007/10/02)
Incubation of dl-α-benzyloxycarboxylic esters with grown cells of a bacterium, Corynebacterium equi IFO 3730, afforded the chiral esters of high optical purities via asymmetric hydrolysis.This reaction has been revealed to have a wide applicability to alkene- and arylalkene-carboxylic esters.
A Stereoselective Synthesis and a Convenient Synthesis of Optically Pure (24 R)- and (24 S)-24-hydroxycholesterols
Koch, Patrick,Nakatani, Yoichi,Luu, Bang,Ourisson, Guy
, p. 185 - 194 (2007/10/02)
A new stereoselective synthesis of optically pure (24 S)-24-hydroxycholesterol (cerebrosterol) and (24 R)-24-hydroxycholesterol, using D- and L-valines as chiral sources, as well as a convenient synthesis, are described.
