Abstract:: An efficient method has been developed for the synthesis of new pyrano[3,2-c] and pyrano[3,2-a]carbazole de-rivatives via a three component reaction of 4-hydroxycarbazole or 2-hydroxycarbazole, isocyanides, and dialkylacetylenedi-carboxylates. Noteworthy features of this protocol include mild reaction conditions, catalyst-free, high atom-economy and high yields.

A new multicomponent reaction has been developed between isocyanides, sulfur and alcohols or thiols under mild reaction conditions to afford O-thiocarbamates and dithiocarbamates in moderate to good yields. The one-pot reaction cascade involves the formation of an isothiocyanate intermediate, thus a catalyst-free synthesis of isothiocyanates, as valuable building blocks from isocyanides and sulfur is proposed, as well. The synthetic procedure suits the demand of a modern organic chemist, as it tolerates a wide range of functional groups, it is atom economic and easily scalable.

Three Component Reaction

A new series of some interesting bispyrazole-thiazole-pyran-2-one heterocyclic hybrids has been efficiently synthesized via a one-pot catalyst-free three-component reaction of α-bromoacetylated pyran-2-one derivatives, thiosemicarbazide, and polysubstituted-1-(1H-pyrazol-4-yl)butane-1,3-diones. This multicomponent procedure has been advantageously applied to prepare a structural diversity of hetero­cyclic hybrids characterized by extensive 1D and 2D NMR spectroscopic studies.
