Organoboron-based asymmetric

In summary, this chapter shows that organoboron-based asymmetric reducing agents, such as K Glucoride (1), K Xylide (2), Alpine-borane (3), Dip-Chloride (4) and oxazaborolidine-catalyzed boranes are highly effective for the reduction of a variety of a-functionalized ketones. We have established a convenient and simple procedure for the preparation of terminal 1,2-diols, a-hydroxy acetals and epoxides with very high optical purity via oxazaborolidine-catalyzed borane reduction using /V-phenylamine-borane complexes as the hydride source. [Pg.132]
