Abstract
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 SN2 displacement of triflates 7, 11. Fluorine was selectively introduced via trans-diaxial epoxide opening with tetrabutylphosphonium fluoride dihydrofluoride (TBPF-DF).
