DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 25, 34 Using proline as starting material and (2R,3R)-tartaric acid as resoln. agent, D-proline was prepd. by an asym. transformation, i.e. D-proline was treated with acetyl chloride, triethylamine and (BOC)2O one after another. Finally the title compd. diphenyl[(R)-2-pyrrolidinyl]methanol [i.e., (2R)-(+)-a,a-diphenyl-2-pyrrolidinemethanol] was obtained through reaction with Ph magnesium bromide and extg. by Et acetate. The total yield was 46%.Except for chemicals metioned above, 22348-32-9 and 100-58-3 are also used. .
