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 envelope 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
从相应的α-羟基酸的酰胺或N-甲基酰胺获得几种旋光的4-恶唑烷酮。研究了溶剂和取代基对其CD的影响。对于这些化合物,确立了包膜构型的优势,通过极性溶剂提高了起皱的程度。对于5-苄基取代的恶唑烷酮衍生物,观察到具有芳环面对恶唑烷酮环的折叠形式。
