ASYMMETRIC PHOTOCHEMICAL REACTION PROCESS |
| 摘要 |
<p>An optically active substance having an optical purity of at least 50% e.e. is obtained with the asymmetric photochemical reaction by preparing a starting, achiral material in a chiral crystalline form and irradiating light to the chiral crystalline form to effect the photocyclization of the starting material.</p> |
