Diacetoxyiodobenzene mediated one-pot synthesis of diverse carboxamides from aldehydes.

A novel, one-pot, and highly facile protocol has been devised for an easy access of a series of novel glycosyl carboxamides from aldehydes using diacetoxyiodobenzene in the presence of ionic liquid at ambient temperature.

Facile route for N1-aryl benzotriazoles from diazoamino arynes via CuI-mediated intramolecular N-arylation

Abstract A facile and high-yielding protocol for diverse benzotriazoles through intramolecular N-arylation of different o-chloro-1,2,3-benzotriazenes using CuI/Cs2CO3 has been developed.

Benzotriazole-Mediated Facile Synthesis of Novel Glycosyl Tetrazole

A facile, simple, and high-yielding synthetic protocol for novel glycosyl tetrazoles has been devised from different carbohydrate-containing amides using benzotriazole methodology under mild reaction condition.

A highly expeditious synthesis of a bicyclic iminosugar using the novel key step of [NMM]+[HSO4]− promoted conjugate addition and Mitsunobu reaction

A simple and highly facile protocol has been developed for the stereoselective synthesis of 1-deoxy-norcastanospermine from readily available D-glucose. N-Methylmorpholinium hydrogen sulphate was seen for the first time as a suitable catalyst for the facile conjugate addition of an amine to a glycosyl olefinic ester. Furthermore, the key step of this strategy is the internal reductive amination of glycosyl azetidine, obtained from glycosyl β-amino alcohol under Mitsunobu reaction conditions.
