A novel palladium-catalyzed decarboxylative cascade cyclization for the assembly of diverse fused heteropolycycles by employing α-oxocarboxylic acids as three-carbon insertion units is reported. This protocol enables the synthesis of isoquinolinedione- and indolo[2,1-a]isoquinolinone-fused benzocycloheptanones in moderate to good yields by the use of different aryl iodides, including alkene-tethered 2-iodobenzamides and 2-(2-iodophenyl)-1H-indoles. Notably, the approach achieves simultaneous construction of both six- and seven-membered rings via sequential intramolecular carbopalladation, C-H activation, and decarboxylation.

Unexpected Smiles! An unusual and highly regioselective synthesis of dibenzoxazepinones by a domino sequence assisted by an unexpected Smiles rearrangement is reported. The process is effective on electronically differentiated phenols and shows a high tolerance to variation in the benzamide substituents. A plausible path for the reaction, supported by preliminary mechanistic data, is offered. Copyright
Synergistic effect of palladium and copper catalysts: Catalytic cyclizative dimerization of ortho-(1-alkynyl)benzamides leading to axially chiral 1,3-butadienes

Two is better than one: In the presence of Pd(OAc)2 and Cu(OAc)2, o-(1-alkynyl)benzamides 1 were converted into bis-iminobenzoisofurans with an axially chiral 1,3-diene 2 unit. The coexistence of both Pd and Cu catalysts was found to be essential for both the cyclizative dimerization process and for the observed unusual cyclization mode. Copyright
Palladium(II)-catalyzed intramolecular diamination of alkynes under aerobic oxidative conditions: Catalytic turnover of an iodide ion

"I" did it: A sequential intramolecular amination/N- demethylation/amidation of internal acetylenes in the presence of a catalytic amount of Pd(OAc)2 and nBu4NI afforded indolo[3,2-c]isoquinolinones under mild aerobic conditions (see
Synthesis of 2-substituted β-cyclodextrin derivatives with a hydrolytic activity against the organophosphorylester paraoxon

β-Cyclodextrin was substituted by an iodosobenzoic acid derivative to create a catalytic hydrolytic activity against neurotoxic organophosphorus agents. The catalytic moiety was introduced on a secondary hydroxy group at the position 2 of a glucose unit.
