The stereochemical course of the asymmetric reduction of ketones by a photosynthetic microbe is largely regulated by light. Thus, we find that the enantioselectivity of the reduction of a,a-difluoroacetophenone with Synechococcus elongatus PCC 7942 increases as a result of illumination with fluoresc

## Abstract The equimolar mixture of __N__‐(hydroxyalkyl)pyrazoles and borane formed boric ester complex, in which the remaining borane was stabilized by the adjacent nitrogen of thr pyrazole ring. The borane complex derived from the chiral pyrazoles such as 3‐phenyl‐__l__‐menthopyrazole reduced __
