A novel N-iodosuccinimide-mediated decarboxylative (4+1) oxidative annulation between 2-vinylpyridine derivatives and malonate monoesters was developed. It offers a new way to construct indolizine derivatives by utilizing malonate monoesters as a C1unit. The alkyl 2,2-diiodoacetate was found to be the active reaction intermediate during the transformation. (Figure presented.).

1-Nitro-2-(phenylthio)ethylene (1) reacts with a variety of N-ylides and N-imines (pyridinium, isoquinolinium, quinolinium, phthalazinium N-ylides and N-imines) in the presence of triethylamine to give the corresponding fused pyrrole and pyrazole derivatives (indolizines, pyrroloisoquinoline, pyrrolophthalazine, pyrazolopyridine, pyrazoloquinoline, and pyrazoloisoquinoline) along with the corresponding 1-nitropyrrolopyridines and 1-nitropyrazolopyridines, respectively, in moderate yields.
The 1,3-Dipolar Cycloaddition Reactions of Heteroaromatic Dicyanomethylides with Phenylsulfinylethene and Bis(trimethylsilyl)ethyne: Synthesis of 1,2-Unsunstituted 3-Cyanoindolizines

Pyridinium and diazinium dicycanomethylides underwent 1,3-dipolar cycloaddition-extrusion reactions with phenylsulfinylethene, producing the corresponding 3-cyanoindolizines in moderate to good yields. 1,3-Dipolar cycloadditions of these ylides with bis(t
