| Research Abstract |
Under these circumstances that biocatalytic transformation is widely used, two approaches, the elaboration of "substrate molecular technology" and "quest of biocatalysts" should be emphasized. The aim of this approach is to find the optimized structure and synthetic routes of substrates, which would be maximally advantageous for both selectivity of enzyme-catalyzed reaction, and the total efficiency to target molecules. As the results through the research, three topics were achieved: 1) the exploration of the structure of alpha-haloketones which would be highly and efficiently reduced by stereoselective whole-cell microorganisms; 2) development of the structure of sugar oxazolines and glycal derivatives which serves free functional groups requisite for regio- and stereoselective transformation such as Ferrier reaction, were established. Based on them, new routes for (R)-terbutaline hydrochloride and rare sugars became available.
