Regioselective Glycosylation: Synthesis of α-Indoline Nucleosides
摘要:
Novel indoline ribonucleosides with the alpha-N-glycoside configuration are synthesized with very high regioselectivily 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.
