Solvent Free Synthesis

A three-component, efficient, and facile procedure has been developed for the synthesis of α-aminonitriles from aldehydes, amines, and trimethylsilyl cyanide using a catalytic amount of magnesium bromide ethyl etherate in the absence of solvent. Rapid formation of products is observed at room temperature in a one-pot procedure under very mild conditions giving excellent yields of the title compounds.Key words: catalyzed Strecker's reaction, α-aminonitriles, magnesium bromide, solvent-free.

Solvent Free Synthesis

The reaction of 3H-indoles with tertiary propargylic alcohols to give functionalized dihydrooxazolo[3,2-a]indoles in good to excellent yields has been developed. This metal- and solvent-free, one-pot tandem assembly proceeds under mild conditions (22–60 °C) and is regio- and stereoselective: either the Z- or E-isomers (relative to the double bond) are alternatively formed depending on other functionalized substituents on the propargylic alcohols.

Poly(N-vinylimidazole) (PVIm), as a biocompatible, efficient, halogen-free, and reusable catalyst, was ‎applied for the solvent-free synthesis of a library of bis(3-indolyl)methanes. The reaction was ‎smoothly carried out under mild conditions, and the crude products were purified easily, and ‎the pure products were obtained in high to excellent yields.‎
