Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent£¬ category: indole-building-block, Which mentioned a new discovery about 30877-30-6
Direct glycosylation: Synthesis of alpha-indoline ribonucleosides
A selective synthesis of alpha-anomers of indoline nucleosides is described. Ribonucleosides of indoline, dimethylindoline and 5-bromoindoline are readily prepared in good yield by reacting indoline bases directly with the protected sugar, 2,3-O-(1-methylethylidene) 5-O-(triphenylmethyl)-D-ribofuranose in dry ethanol or methylene chloride in presence of molecular sieves at 40-60C.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 30877-30-6, help many people in the next few years.category: indole-building-block
