Resin-bound (succinimid-1-yloxycarbonylmethyl)triphenylphosphonium ylide - A synthon for rapid access to diverse heterocycles under microwave heating

The synthesis of a novel and versatile resin-bound (succinimid-1- yloxycarbonylmethyl)triphenylphosphonium ylide is described. The use of this resin to the synthesis of several diverse heterocycles, whilst allowing for ease of workup, is reported. Georg Thieme Verlag Stuttgart.

Rapid Access of Alkynyl and Alkenyl Coumarins via a Dipyridinium Methylide and Propargylamine Cascade Reaction

A DMAP-catalyzed cascade approach allowing facile assembly of alkynyl coumarins is reported. By virtue of reactive o-AQM (in situ generated from modular propargylamine) and a new synthetic equivalent of acyl carbene (from pyridinium ylide), the reaction proceeds smoothly to afford a variety of alkynyl coumarins in good-to-excellent yields. This transition-metal-free and oxidant-free process features moderate functional group tolerance, particularly the-Br group; thus, this protocol circumvents the inherent shortcomings of the existing Sonogashira coupling of coumarin triflates. This versatile method is also found to be applicable to the preparation of β-alkenyl coumarins, resembling the outcomes of the current Heck-type coupling reaction.

Pd/Indanone-Based Ligands: An Efficient Catalyst System for Ullmann-Type, Suzuki-Miyaura, and Mizoroki-Heck Cross-Coupling Reactions with Aryl Tosylates and Aryl Halides

2-Hydroxyindan-1-ones have been efficiently synthesized and successfully applied as ligands in Pd-catalyzed Ullmann type, Suzuki-Miyaura, and Mizoroki-Heck cross-coupling reactions with aryl tosylates and aryl halides. The ligands are air- and moisture-stable and have shown high catalytic activity with Pd(OAc) 2 in these cross-coupling reactions. The system tolerates a variety of functional groups in the product and can be re-used at least three times with maximum efficiency..
