Efficacy of radical reactions of isocyanides with heteroatom radicals in organic synthesis [PDF]

open access: yesBeilstein Journal of Organic Chemistry
Isocyanide is a promising synthetic reagent not only as a one-carbon homologation reagent but also as a nitrogen source for nitrogen-containing molecules.

Studies on the interaction of isocyanides with imines: reaction scope and mechanistic variations [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2014
The interaction of imines with isocyanides has been studied. The main product results from a sequential process involving the attack of two units of isocyanide, under Lewis acid catalysis, upon the carbon–nitrogen double bond of the imine to form the 4 ...

Synthesis of pyrrole-fused dibenzoxazepine/dibenzothiazepine/triazolobenzodiazepine derivatives via isocyanide-based multicomponent reactions [PDF]

open access: yesBeilstein Journal of Organic Chemistry
An efficient and facile synthesis of pyrrole-fused dibenzoxazepine/dibenzothiazepine/triazolobenzodiazepine derivatives was developed through the isocyanide-based multicomponent reaction of isocyanides, gem-diactivated olefins, and cyclic imines such as ...

N-Halosuccinimide enables cascade oxidative trifluorination and halogenative cyclization of tryptamine-derived isocyanides [PDF]

open access: yesNature Communications
Both the pyrroloindoline core and N–CF3 moiety hold significant importance in medicinal chemistry. However, to date, no instances of constructing N–CF3-containing pyrroloindolines have been reported.
