Abstract
| - Both (4S-(+)-3-(isocyanoacetyl)-4-(phenylmethyl)-2-oxazolidinone(R)-1 and its enantiomer(S)-1 havebeen synthesized as potentially useful synthons in asymmetricsynthesis. Optically active (+)-5-(3,4-dimethoxyphenyl)-4-[[N-[(4S)-2-oxo-4-(phenylmethyl)-2-oxazolidinyl]]carbonyl]oxazole (S)-2 andits enantiomer (R)-2 obtained by treating3,4-dimethoxybenzoyl chloride with (S)-1 and(R)-1,respectively, in the presence of the nonionic superbaseP(MeNCH2CH2)3N, have highfluorescencequantum yields. The molecular structure of(S)-2 obtained by X-ray means is alsopresented.
