Enzymatic desymmetrization of 2,5-dideoxystreptamine precursors
摘要:
The stereoselective enzymatic acylation of meso-6,7-diazabicyclo[3.2.1]oct-6-ene-2,4-diol 4 and meso-4,6-diazidocyclohexane-1,3-diol 5 in organic media gave the corresponding monoesters in high enantiomeric excess. The hydrolysis of the corresponding diacetate derivatives in the presence of a different set of enzymes provided the same monoesters. The products are precursors of dideoxystreptamine, an aminocyclitol found in synthetic aminoglycoside antibiotics. (c) 2006 Elsevier Ltd. All rights reserved.
