Optically active photopyridones possessing synthetic versatility are
obtained conveniently by lipase-catalysed enantioselective acylation or
hydrolysis of racemic photopyridones, and the absolute configurations
are determined by chemical correlation, X-ray crystallographic and CD
spectral analyses.
通过脂肪酶催化外消旋光吡啶酮的对映体选择性酰化或水解,可方便地获得具有合成多功能性的光学活性光吡啶酮,并通过化学相关性、X 射线晶体学和 CD 光谱分析确定其绝对构型。
