The reaction of the titanium enolate of a 2-pyridylthioester derived from (R)-3-hydroxybutyric acid with chiral imines affords 3,3'-anti-3,4-trans configurated β-lactams in a highly selective fashion. The methodology has been applied to the synthesis of a

Two new compounds of β-amino alcohol are obtained using (R) - (+) - α-methylbenzylamine as starting material which is converted into two amines. Each of these compounds reacted in excess with a 1: 1 mixture of cis and trans-limonene oxide in the presence of water as a catalyst. The products obtained show that β-amino alcohol derived from trans-limonene oxide is obtained and unreacted cis-limonene oxide from the reaction mixture as well as the amine is attained. Whereas the addition of the synthesized carbamate of the same primary amine over the 1: 1 mixture of cis and trans -limonene oxide in the presence of water results in the hydrolysis product and the recovery of unreacted trans-limonene oxide.

Manganese complexes with tridentate PNN ligands have been synthesized as catalysts for hydrogenative cross-coupling reaction of nitriles and amines to form secondary imines. This reaction afforded a variety of unsymmetrical secondary imines in good yields with excellent selectivity. Investigation of catalyst intermediates indicated that an amido manganese complex may be the active catalyst species for this reaction. (Figure presented.).
