M. Browne et al., TRANS DIASTEREOSELECTIVE SYNTHESIS OF 3-ALKYL SUBSTITUTED BETA-LACTAMS VIA THE ACID CHLORIDE-IMINE REACTION OF NONACTIVATED ACID-CHLORIDES, Tetrahedron letters, 36(15), 1995, pp. 2555-2558
New conditions for the acid chloride-imine reaction of nonactivated al
kyl acid chlorides provide 3-alkyl substituted beta-lactams in good yi
elds with high trans selectivity.
