Novel indoline ribonucleosides with the alpha-N-glycoside configuration are synthesized with very high regioselectivity in 90-96%yield, using TMS protected indolines and 2,3-O-(1-methylethylidene)-5-O-(triphenylmethyl)-alpha/beta-D-ribofuranose. The structures of these ribonucleosides were elucidated with X-ray crystallography as well as 2D (NOESY, COSY, and HMQC) NMR spectroscopy.
