Preparations and Crystal-Structures of the 2-Oxides of Some Octahydro-3,2,1-Benzoxathiazines and Octahydro-2h-3,1,2-Benzoxazaphosphorines

Abstract

The cis -and trans-fused 1-benzyl-1,4,4a,5,6,7,8,8a-octahydro-3,2,1- benzoxathiazine 2- oxides and cis - and trans-fused 1-benzyl-2-phenyl-1,4,4a,5,6,7,8,8a-octahydro-2H-3,1,2-benzoxazaphosphorine 2-oxides have been prepared from the cis- and trans-2-benzylaminocyclohexanemethanols and their structures have been determined by n.m.r .and crystallographic methods.
