  Benzylidene-Oxazolones as Molecular Photoswitches

  摘要：

  The synthesis and photochemical study of a family of molecular switches inspired by the green fluorescent protein (UP) chromophore is presented. These compounds can be easily synthesized, and their photophysical properties may be tuned. Due to their efficient photoisomerization and high stability, these compounds can be switched on/off by using light and heat or light with different wavelengths.

• Process for producing N-acylphenylalanines

  An N-acyl-substituted or unsubstituted phenylalanine is prepared by hydrolyzing a 2-substituted-4-substituted or unsubstituted benzylidene-5-oxazolone with an alkali, adjusting the reaction system containing its hydrolysis product with acid to a pH of 5 - 9 and reducing the resultant reaction solution catalytically in the presence of a palladium or platinum reducing catalyst. The reduction is carried out continuously without isolating the alkaline hydrolysis product, i.e., a substituted or unsubstituted N-acylaminocinnamic acid from the reaction system. The catalyst can be recovered after completion of the reduction and used repeatedly without additional treatment and without any observed lowering in its catalytic activity. Accordingly, the reductions using the recovered catalyst may proceed at pratically the same rate as reductions using a fresh catalyst.

  一种 N-酰基取代或未取代的苯丙氨酸是通过以下方法制备的：用碱水解 2-取代-4-取代或未取代的亚苄基-5-恶唑酮，用酸将含有其水解产物的反应体系调节到 pH 值为 5 - 9，然后在钯或铂还原催化剂存在下催化还原所得到的反应溶液。还原反应是连续进行的，无需从反应体系中分离出碱性水解产物，即取代或未取代的 N-酰基氨基肉桂酸。 催化剂可在还原完成后回收并重复使用，无需额外处理，也不会降低其催化活性。因此，使用回收催化剂进行还原的速度与使用新催化剂进行还原的速度基本相同。
