Enantioselective Spirocyclopropanation of para-Quinone Methides Using Ammonium Ylides
The use of Cinchona alkaloid-based chiral ammonium ylides allows for the first highly enantioselective and broadly applicable spirocyclopropanation reactions of para-quinone methides. This strategy provides a straightforward protocol toward the chiral spiro[2.5]octa-4,7-dien-6-one skeleton, which is a frequently found structural motif in important biologically active molecules.
متن کاملOne-pot synthesis of Benzimidazole derivatives under microwave Irradiation and solvent-free condition
A simple, fast, efficient and environmentally friendly method for synthesis of benzimidazole and its 2-alkyl, aryl and heteroaryl substituted derivatives was developed using zeolite HY. Two component cyclolcondensation of 1,2-phenylenediamine (o-phenylenediamine) and commercially available carboxylic acids catalyzed by zeolite HY without any solvent, under microwave irradiation led to formation...
متن کاملMicrowave-assisted Synthesis of Nـ alkyl 2ـ ketomethyl quinoline Derivatives Under Solvent-free Conditions
A series of Nـ alkyl 2ـ ketomethylquinoline derivatives were synthesis by reaction of benzoyl chloride derivatives with Nـ methyl quinaldine iodide in the presence of triethyl amine under microwave irradiation. Enaminone form of the product study by spectroscopy method. The result revealed the Nـ alkyl 2ـ ketomethylquinoline the fixed enaminone tautomer.
متن کاملINTERMOLECULAR APPLICATIONS OF o-QUINONE METHIDES (o-QMs) ANIONICALLY GENERATED AT LOW TEMPERATURES: KINETIC CONDITIONS
There existmany fundamental andphilosophical truths in theuniverse.Among these is the notion that the value of an item is determined by its inherent characteristics and its surrounding environment. For example, a fishing pole near the sea is a useful tool, but when relocated to the desert its usefulness decreases. o-Quinone methides (o-QMs) are highly reactive species with short lifetimes becau...
متن کاملSynthesis of Metallophthalocyanines Under Solvent Free Conditions Using Microwave Irradiation
Phthalocyanine complexes of Cu, Co, Ni, Fe, Zn, Pd, Pt and Ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.
