Abstract: | From O-glycosyl trichloroacetimidates , , and and activated benzene derivatives C-aryl glycosides were obtained by mild Lewis acid catalysis. In most cases only one stereoisomer was formed, however, the α-alkoxyalkyl transfer took place not always by inversion of configuration at the anomeric center. |
