A series of di substituted indole and tri substituted pyrrole derivatives were synthesized efficiently by using I2/K2CO3 in DMSO. The novel synthesis method offers the advantage of mild reaction conditions, operational simplicity, higher yields. The method is functional group tolerant and provides quick access to medicinally significant compounds in moderate to high yields.

experimental part, p. 204 - 207 (2012/04/17)
A facile amination of 1,4-diketones with ammonium acetate has been achieved by mechanochemical grinding assisted by infrared irradiation in the presence of silica gel. The wastes are reduced and the energy resources saved..
