Abstract

Several marine-derived fungi were evaluated by the bioreduction of 2-azido-1-phenylethanone 1, and the strains A. sydowii CBMAI 935 and M. racemosus CBMAI 847 were selected for the reduction of 2-azido-1-phenylethanone derivatives 2-4. Whole cells of A. sydowii CBMAI 935 promoted the reduction of 2-azido-1-phenylethanones 1-4 with high selectivities to yield the (S)-2-azido-1-phenylethanols 1a-4a. Bioreduction of compounds 1-4 by M. racemosus CBMAI 847 led to (R)-2azido-1-phenylethanols for 1, 2 and 4 and (S)-2-azido-1-phenylethanol 3. Enantiomerically enriched 2-azido-1-phenylethanols 1a-4a and phenylacetylene 5 were applied in the synthesis of b-hydroxy-1,2,3-triazoles using CuSO4 and sodium ascorbate leading to regioselective formation of enantioenriched 1,4-disubstituted 1,2,3-triazole compounds 1b-4b.
