Mixing of powdered chiral hosts and achiral guest compounds gives inclusion complexes in which the latter molecules are arranged in a chiral form. Freezing of the chirality of the guest compounds by photoirradiation in the solid state gives optically active photoreaction products.

Optically active β-lactams and/or oxazolidinones have been obtained selectively by photoirradiation of a 1:2 inclusion complex of phenylglyoxylamide with an optically active host derived from tartaric acid.Delicate selectivity which is dependent on substituents in the phenylglyoxylamide and the host is described.
OPTICAL ACTIVITY OF LACTONES AND LACTAMS-II CHIROPTICAL PROPERTIES OF 4-OXAZOLIDINONES

Several optically active 4-oxazolidinones were obtained from amides or N-methylamides of corresponding α-hydroxy acids.The influence of solvent and substituent on their CD was studied.The predominance of the envelpe conformation was established for these compounds, the degree of puckering being enhanced by polar solvents.The folded form with the aromatic ring facing the oxazolidinone ring was observed for 5-benzyl substituted oxazolidinone derivatives.
