Provided is a method of preparing a silylative-reduced N-heterocyclic compound by reducing an N-heteraromatic compound including a sp2 hybridized nitrogen atom while simultaneously introducing a silyl group into a beta-position with respect to a nitrogen atom of the N-heteroaromatic compound, using a silane compound, in the presence of an organoboron catalyst.

Secondary benzylic alcohols were kinetically resolved by rabbit gastric lipase-mediated acylation with isopropenyl acetate. Among all the substrates tested, a high enantioselectivity was observed only for 1-[2-(6-methoxy)naphthyl]ethanol 3a (E>500). Allylic alcohols 14a and 15a were also efficiently resolved (E = 26 and 51 respectively).
