T. Kitazume et al., A HIGHLY STEREOCONTROLLED SYNTHETIC APPROACH TO 1,6-DIDEOXY-6,6-DIFLUOROAZASUGAR DERIVATIVES, Tetrahedron : asymmetry, 5(6), 1994, pp. 1029-1040
The synthetic utility of (alpha R, 6R)- or (alpha R, hylbenzyl)-6-difl
uoromethyl-5,6-dihydro-4-pyridone 2, which was produced from the react
ion of 1-methoxy-3-[(trimethylsilyl)oxy]-1,3-butadiene and (alpha R)-
or (alpha S)-N-(2,2-difluoroethylidene)methylbenzylamine 1, is describ
ed. These materials are found to be potential intermediates for a high
ly stereocontrolled synthesis of 1,6-dideoxy-6,6-difluoroazasugar anal
ogues.
