摘要:We compare herein the scope of three copper (I) catalysts on the synthesis of various 1,4-disubstitued-1,2,3-triazolo-carbanucleosides through a microwave (and thermic) assisted Huisgen 1,3-dipolar cycloaddition. The tetrakis(acetonitrile)copper hexafluorophosphate ([Cu(CH3CN)4]P...

摘要:Our goal was to synthesise this compound by glucosylation of p-tyrosol. The 74% yield of the reaction was not satisfactory and instead of optimising the procedure, we preferred to purify the product. This was achieved by high performance centrifugal partition chromatography with ...
