Ultrasonic irradiation and the homo- and hetero-Diels-Alder reaction

The effects of ultrasound on the hetero- and homo-Diels-Alder reactions have been investigated varying ultrasonic source and solvent. Irradiation enhances both reactions minimally; however, while this appears to be due to cavitation in the homo Diels-Alde

Synthesis and Characterization of Pheox– and Phebox–Aluminum Complexes: Application as Tunable Lewis Acid Catalysts in Organic Reactions

Pheox– and Phebox–aluminum complexes were synthesized and subsequently characterized by spectroscopic analysis. These complexes acted as Lewis acid catalysts, and their catalytic activities were controlled by using the Pheox, Phebox, and heteroatom ligands. The Pheox–aluminum complex exhibited an opposite substrate selectivity to AlCl3 in a competitive hetero-Diels–Alder reaction between electron-rich and electron-deficient aldehydes.

Control of selectivity in the generation and reactions of oxonium ylides

Dirhodium catalyzed reactions of aryl-substituted tetrahydropyranone diazoacetoacetates produce ylide intermediates that unexpectedly yield two oxabicyclo[4.2.1]-nonane diastereoisomers, but a single diastereoisomer is formed by increasing the steric bulk of the aryl substituent.

CHIRAL DISULFONIMIDES

Chiral disulfonimides having the formula I to III, wherein at least one of the groups A and B in the compound of formula I, C and D of the compound in formula II, and E and F of the compound in formula III is a chiral group, or E and F together form a chi

Heterogeneous Lewis acid catalysis with self-organized polymeric rare earth arylsulfonates under solvent-free conditions

Polymeric rare earth arylsulfonates, easily prepared from rare earth triisopropoxides and biphenyl-4,4'-disulfonic acid (BPDSA) or 1,3,5-triphenylbenzene trisulfonic acid (TPTSA) in a self-organization manner, were found to work as an efficient heterogene

A Lewis Base-catalyzed hetero Diels-Alder reaction between aldehydes and the Danishefsky's diene

A lithium methoxide-catalyzed hetero Diels-Alder reaction of aromatic and aliphatic aldehydes with 1-methoxy-3-trimethylsilyloxy-1,3-butadiene (Danishefsky's diene) is described. It proceeds through the Mukaiyama-Aldol reaction pathway and affords the cor

Hetero diels-alder type reactions between danishefsky's dienes in the presence of lewis base catalysts. An efficient method for the synthesis of substituted 2,3-dihydropyran-4-ones

Alkoxy anion such as methoxide anion works effectively as Lewis base catalyst to activate silicon-carbon bond of 1-methoxy-3-trimethylsilyloxy-1,3-butadiens (Danishefsky's dienes) in the reaction between aldehydes and ketones. By using Lewis base as catal

Hetero-diels-alder reaction catalyzed by self-organized polymeric rare earth complexes under solvent-free conditions

-2-Substituted 2,3-dihydropyran-4-one derivatives were conveniently synthesized under solvent-free conditions by Lewis acid-catalysis with a polymeric scandium sulfonate complex, which can be prepared in a self-organized manner in one step and successfull

Dramatically synergetic effect of carboxylic acid additive on tridentate titanium catalyzed enantioselective hetero-Diels - Alder reaction: Additive acceleration and nonlinear effect

This paper describes the successful development of a group of highly efficient chiral tridentate titanium catalysts for hetero-Diels -Alder reaction of Danishefsky's diene and a variety of aldehydes through ligand and additive diversity. Dramatically syne

Nafion-H-catalyzed Mukaiyama aldol condensations and hetero Diels-Alder reactions using aldehydes and imines. Part 15: General synthetic methods

Nafion-H catalyzes the Mukaiyama aldol condensation between aromatic aldehydes and the Danishefsky diene whereas the corresponding imines directly undergo hetero Diels-Alder cyclization to form 2,3-dihydro-γ-pyridones. Some chiral acetal derived aldehydes
