Studies in reductive amination. Part II. Aminopivalic acid from hydroxypivalic acid
Abstract
Low yields (ca. 20%) of aminopivalic acid result when hydroxypivalic acid is catalytically hydrogenated in aqueous ammonia at 225° and 220 atmospheres pressure. Dealdolisation products also are produced in substantial quanitities, and in the absence of catalyst and hydrogen these are formed exclusively.
