Article abstract of DOI:10.1002/hlca.19940770521

Insertion of the glycosylidene carbenes, derived from the gluco- and the manno-diazirines 1 and 2, into the Sn-H bond of R3SnH (R = Bu of Ph) leads to the fully substituted stannoglycosides 3-8 (53 - 77percent).The 1,2-cis-configurated products are formed
