β¦ Synopsis
Swmna~: A nwnber of optically active organosiZicon compounds are prepared by the kydrosilylation of (-)-B-pinene. Tke reduction of several pro-ckiral ketones with the ckiral silane III was investigated.

Some chiral acetals are cleaved by organoaluminum reagents. The products are formed diastereoselectively, and the removal of the chiral auxiliary affords optically active alcohols. A recent communication by Bartlett, Johnson and Elliott1 on the acetal derived from (-)-(2$4\_R)-2,4-pentanediol has pr
Chiral cobalt--diamine complexes have been prepared and tested in catalytic reduction of 13-ketoesters and ketones with molecular hydrogen or hydride transfer reduction (HTR). Modest to high conversions, but low e.e.s were obtained in the first case, whereas encouraging e.e.s (up to 58%) but low con
