A facile and efficient oxidative functionalization of vinyl azides with aldehydes furnishing a diverse array of β-acylated enaminones was developed. The cross coupling was accomplished in the presence of CuCl2•2H2O/TBHP...

With water as solvent, K2S2O8 mediated facile and efficient synthesis of β‐keto sulfones through oxysulfonylation of vinyl azides with sodium sulfinates is described. The novel procedure has the advantages of being environmentally benign, mild reaction conditions, short reaction time, easy and simple operation, wide tolerance of functional groups, which establish the practical application of this methodology.

A novel, facile and eco-friendly synthesis of quinoxalines from [Formula: see text] and 1,2-diamines was developed. An attractive feature of this protocol is that the desired products could be generated efficiently in water and without any catalyst, which is in accordance with the aim of green chemistry. A plausible mechanism has been proposed.
