dichloroacetamide-tethered ketones using pyrrolidine, AIBN and TTMSS under microwave activation gave 2-azabicyclo[3.3.1]nonan-3,6-diones. In a five-minute one-pot process, after the generation of an enamine, intramolecular addition of a...
Six-membered nitrogen ring formation by radical cyclization of trichloroacetamides with enones. A synthetic entry to cis -perhydroisoquinoline-3,6-diones
Intramolecular reactions between 1-(carbamoyl)dichloromethyl radicals and enones acting as radical acceptors are reported for the first time. The Bu3SnH promoted 6-exo reaction of trichloroacetamides with enones, avoiding the 1,5-hydrogen transfer, constitutes a new synthetic entry to cis-perhydoisoquinoline-3,6-diones.
