  Kinetic Resolutions and Enantioselective Transformations of 5-(Acyloxy)pyrrolinones Using Candida antarctica Lipase B:  Synthetic and Structural Aspects

  摘要：

  Various 5-(acyloxy)pyrrolinones have been prepared in enantiomerically pure form by means of an enzymatic resolution or an asymmetric transformation. Either enantiomer is obtained using the same enzyme, Candida antarctica lipase B, by modification of the procedure from transesterification to esterification. N-Acyl-5-(acyloxy)pyrrolinones 1 (R-2 = acyl) are synthesized by applying this method with 100% yield and >99% ee. To rationalize the observed enantioselectivity and the substituent effects of these reactions both empirical models and molecular modeling studies have been used, and a qualitative agreement was found between the results from these studies and the experimental results.

  日期：2006.11.1

  The ceric ammonium nitrate promoted oxidations of 4,5-diphenyloxazoles and oxazoles with various substitution patterns have been investigated. This transformation results in the formation of the corresponding imide in good yield and tolerates a wide variety of functional groups and substituents on the oxazole moiety. [reaction: see text].
