Alkylation of dibutylstannylene complexes of .3,4,6-tri-g-benzyl-Pmannopyranose, methyl 6-e-trityl-a-E-mannopyranoside and methyl a-pmannopyranoside gives respectively g-g-mannopyranoside and 3-g-alkyl derivatives with high selectivity. We have been engaged in an investigation of the synthesis of g
