Jd. Armstrong et al., AN EFFICIENT ASYMMETRIC-SYNTHESIS OF -3-AMINO-2,3,4,5-TETRAHYDRO-1H-[1]BENZAZEPIN-2-ONE, Tetrahedron letters, 35(20), 1994, pp. 3239-3242
Two approaches for the asymmetric preparation of (-)- or (+)- alpha-am
inobenzlactam 1 are described. One route is based on the asymmetric hy
drogenation of enamide 5 and the other on the racemization/resolution
of (+/-)-1.
