Catalytic Diazosulfonylation of Enynals toward Diazoindenes via Oxidative Radical-Triggered 5-exo-trig Carbocyclizations

Catalytic diazosulfonylation of enynals with arylsulfonyl hydrazides has been established by using tert-butyl hydroperoxide (TBHP) as the oxidant with tetrabutylammonium iodide (TBAI) under a convenient system. The reaction occurred through oxidative radical-triggered 5-exo-trig carbocyclization cascading to afford sulfonylated diazoindenes regioselectively. The new diazosulfonylation reaction features a broad substrate scope, readily accessible starting materials, and a simple one-pot process.

Synthesis of organoselenyl isoquinolinium imidesviairon(iii) chloride-mediated tandem cyclization/selenation ofN′-(2-alkynylbenzylidene)hydrazides and diselenides

This report describes the synthesis of organoselenyl isoquinolinium imides through a tandem cyclization betweenN′-(2-alkynylbenzylidene)hydrazides and diselenides. The reaction was carried out at room temperature under an ambient atmosphere using cheap iron(iii) chloride as the metallic source. The strategy shows good tolerance to a broad range ofN′-(2-alkynylbenzylidene)hydrazides and diselenides, and forms C-N and C-Se bonds in one step. The obtained product is further transformed into a bioactiveH-pyrazolo[5,1-a]isoquinoline skeleton easilyviaa silver catalyzed [3 + 2] cycloaddition.
