Preferred conformation of C-glycosides. 14. Synthesis and conformational analysis of carbon analogs of the blood groupp determinant H-type II

Article abstract of DOI:10.1021/jo00112a040

The syntheses of C-trisaccharides 1-4, carbon analogs of the human blood group determinant H-type II, have been achieved in a flexible and efficient manner. Vicinal coupling constants in the ¹H NMR spectrum provide experimental evidence that ea
