Enantiospecific axial-to-point chiral transfer in light-induced transformations was efficient under elevated pressure at high temperatures. Model photoreactions with atropisomeric compounds showed higher enantioselectivity in the photoproducts under elevated pressure. The ee values in the photoproducts were rationalized based on the increased stability of optically pure atropisomeric compounds at elevated pressure, even at high temperatures.
在高温高压下,光诱导转化中对映体轴到点的手性转移是有效的。具有非对映异构体化合物的模型光反应在高压下显示出更高的光产物对映选择性。光产物的 ee 值可以根据光学纯非对映异构体化合物在高压下甚至在高温下的稳定性增加来合理化。
