Abstract

d-(–)-Camphorquinone imines prepared using methanolic ammonia, ethanol amine, exo-(–)-bornylamine, ethylene diamine, propylene diamine, and trans-(R,R)-1,2-diaminocyclohexane, upon reduction using sodium borohydride in methanol, give the corresponding chiral exo amino alcohol and diamine derivatives in good yields (75–95%).
