2008 Amines Q 0120 Cobalt-Catalyzed Reductive Mannich Reactions of 4-Acryloylmorpholine with N-Tosyl Aldimines. — The process affords the acyclic anti-β-aminoamides (III) as the major products. It complements existing syn-selective reactions and Morken's methol- ogy that gives β-lactams. It also shows higher diastereoselectivities compared with ex- isting anti-selective reductive Mannich reactions. — (PRIETO, O.; LAM*, H. W.; Org. Biomol. Chem. 6 (2008) 1, 55-57; Sch. Chem., Univ.
