摘要:

The conformations of crystalline 6-C-(benzothiazol-2-yl)sulfonyl-6-deoxy-1,2:3,4-di-O-isopropylidene-α-D-galactopyranose (1) andSR-6-deoxy-1,2:3,4-di-O-isopropylidene-6-C-(2-pyridyl)sulfinyl-α-D-galactopyranose (2) have been determined by X-ray diffraction. The crystal structure of1belongs to the monoclinic P21space group witha= 10.779(4),b= 10.431(6),c= 10.258(6) Å) and β =113.51(2)°C. The crystal structure of2belongs to the tetragonal space P41212 witha= 10.652(2) andc= 33.037(4) Å. The molecular features of these two compounds are compared with those of the related 6-S-(benzoxazol-2-yl)-1,2:3,4-di-O-isopropylidene-6-thio-α-D-galactopyranose (3).
