The possibilities of synthetic utilization of enantioselective reducti
ons of prochiral ketones catalyzed by 1,2,3-oxazaborolidines are shown
on a series of representative pattern reactions. The presented reacti
ons are evaluated from the point of view of reaction conditions, i.e,
type and amount of the used catalyst, reduction agent (BH3.THF, BH3.SM
e(3), catecholborane), solvent (THF, toluene, CH2Cl2, i.a.) or activat
or (simple alcohols or ethanolamine).
