Chemoenzymatic enantiodivergent synthesis of 1,2-dideoxy-2-amino-1-fluoro-allo-inositol
摘要:
Both enantiomers of dideoxyfluoroamino inositols (+)-9 and (-)-9 were synthesized from bromocyclohexadiene cis-diol 1 obtained by microbial oxidation of bromobenzene with toluene dioxygenase. Selective introduction of the amino group was achieved through S(N)2 displacement of triflates 7, 11. Fluorine was selectively introduced via trans-diaxial epoxide opening with tetrabutylphosphonium fluoride dihydrofluoride (TBPF-DF). (C) 1999 Elsevier Science Ltd. All rights reserved.
