Structure and conformation of ethyl 6-O-benzoyl-4-iodo-2,3,4-trideoxya-α-D-hex-2-enopyranoside
Abstract
Crystals of the title compound were orthorhombic, space group P212121, a= 4.652(7), b= 17.577(15), c= 19.857(19)Å, Z= 4. The structure was solved by heavy-atom methods from 1 067 observed reflections measured on a diffractometer and refined by full-matrix least squares to R 0.095. The six-membered pyranose ring has a slightly distorted half chair (0H5) conformation.
