Ligand free Pd catalyzed cyclization-influence of steric hindrance

Synthesis of sultams was performed using ligand free palladium catalyst following Heck cyclization. The diverse synthesized intermediates in this strategy includes halogenated sulfonyl chloride, alkyl/aryl sulfonamides, N-alkylation using halogenated alke

Nickel-catalyzed regio- and enantioselective annulation reactions of 1,2,3,4-benzothiatriazine-1,1(2H)-dioxides with allenes

(Figure Presented) Extrusion of N2:1,2,3,4-Benzothiatriazine1,1 (2H)-dioxides reacted with alienes in the presence of a nickel (0)/(R)-quinap complex to produce a variety of substituted 3,4-dihydro-1,2-benzothiazine1,1 (2H)-dioxides in a regio- and enantioselective fashion. An intermediate nickelacycle was generated through denitrogenative activation of the triazo moiety which allowed the intermolecular incorporation of an aliene group. quinap = 1-(2diphenylphosphino-1-naphthyl)isoquinoline.
