Two efficient, metal free reagent systems, PhI(OAc)2-I2 (method A) and IBX-I2 (method B), for stereoselective synthesis of trans-2-deoxy-2-iodoglycosylacetates and O-iodobenzoates respectively from differently protected glycals have been developed. They are compatible with a variety of protecting groups and various functional groups at 2C-position. Hexose-3,2-enolone 8 is obtained directly from 2-acetoxy glycal 5 by method A. An application to modified method B has been shown by synthesis of a diastereomerically pure α-glycosyl ortho-hexynylbenzoate 12, a glycosyl donor from 3,4,6-tri-O-acetyl-D-glucal in two steps that has been further utilized in the synthesis of glycosides 13–18.
