Prochiral oxoamide

There are two ways of obtaining chiral substances using a chiral crystal environment. One is to produce the chiral compounds from the prochiral ones, and the other is to obtain the chiral compounds from racemic ones. The former method is called absolute asymmetric synthesis, since the asymmetry is introduced from the physical conditions such as the chiral crystal environment. Several examples [ 1 -7] have been reported since the first example of the chiral polymer produced in the photopolymerization of the chiral monomer crystal [8]. We also observed that chiral 3-lactam compounds were produced from the prochiral oxoamide crystals [9,10].
