Convenient Synthesis

Convenient synthesis of phosphinecarboxamidein by hydrophosphination of isocyanates (and isothiocyanates) was achieved without catalyst and solvent. This system shows shorter reaction time, high yield, and good functional group tolerance.

Convenient Synthesis

A convenient synthesis of the tetrasaccharide repeating unit of theO-antigen ofShigella boydiitype 9 has been achieved in excellent yield using a [2 + 2] block glycosylation strategy. TEMPO-mediated selective oxidation of the primary alcohol of the tetrasaccharide derivative8to the carboxylic group followed by deprotection of the functional groups furnished target tetrasaccharide1as its 4-methoxyphenyl glycoside in high yield.
