A novel, one-pot allylboration-Heck reaction of 2-bromobenzaldehydes has been developed for the general and efficient synthesis of 3-methyleneindan-1-ols. Modification of the one-pot procedure to include chiral Brønsted acid catalyzed allylation has allowed the preparation of these building blocks in high enantioselectivity and excellent yields.

An efficient isocyanide-based synthesis of S-thiocarbamates was discovered and thoroughly investigated. The new reaction protocol is a one-pot procedure allows the direct conversion N-formamides into thiocarbamates by initial dehydration with p-toluene sulfonyl chloride to respective isocyanide subsequent addition sulfoxide component. Contrary recent literature, which also uses isocyanides as s...

an efficient and environmentally friendly procedure for one-pot synthesis of 13-acetyl-9-methyl-11-ox-8-oxa-10,12-diazatricyclo [7.3.1. ] trideca-2,4,6-triene from salicylaldehyde, acetylaceton and urea via biginelli condensation and intramolecular michael-addition by using magnesium bromide as an expensive and easily available catalyst under solvent-free condition is desired. the structural el...

One of the important Multi-component reaction (MCRs) is the synthesis of dihydropyrano chromene derivatives by one-pot reaction. In this research, an inexpensive and effective one pot three component procedure with good yields for the synthesis of dihydro pyrano chromenes is reported. In this method, the synthesis of pyrano chromene derivatives was followed by using 4-hydroxycoumarin, malononit...
