TRANSITION METAL MEDIATED, STEREOSELECTIVE HIGHER-ORDER [6+4] AND DIELS-ALDER [4+2] CYCLOADDITION REACTIONS: SYNTHESIS OF NOVEL 2-SILYL SUBSTITUTED-1,3-DIENYL COMPOUNDS AND THEIR DOMINO REACTIONS
… extensively their reactivities in Diels-Alder reactions. Based on the studies with cobaloxime chemistry, we concluded that increased exo selectivities were possible with the insertion of the transition metals in the 2-position of the diene moiety. In the first part of this study, we will …

Asymmetrische Synthese von Thiadecalinen : Organokatalytische Dominoreaktionen kombiniert mit intramolekularen Michael-Reaktionen
… substituted thiadecalins using organocatalytic domino-reactions and intramolecular Michael-additions is presented. The combination of organocatalytic domino-reactions and intramolecular Michael-reactions leads to the formation of four new bonds and allows the control of six stereogenic centers. …

Keteneylidenetriphenylphosphorane as a Versatile C-2 Building Block Leading to Tetronic Acids with Potential Herbicidal and anti-HIV Activity
… Since acyl ylides enter into Wittig alkenation reactions far more quickly than the starting ylide, multi-component or domino reactions between the latter and a carbonyl compound becomes possible leading to beta,gamma-unsaturated carbonyl derivatives. A further strength of …

Asymmetrische Organokatalyse zu Alpha-Fluorierung von Aldehyden und Ketonen und zur Synthese von Cyclohexencarbaldehyden via Dominoreaktionen
… capable to catalyze a broad variety of different reactions, which explains increasing application of these catalysts in organic synthesis. In particular, amine-catalyzed domino reactions can be easily designed by combination of the enamine and iminiumion activation steps to assemble complex …

New Methods for the α-Functionalization of Thioesters and Activated Hydrazones and an Application Toward the Total Synthesis of Apratoxin D
<p>Cascade reactions, also referred to as domino reactions, have been widely used for the formation of carbon-carbon bonds. This type of reaction has the potential to circumvent protection and deprotection steps, shortening an overall synthetic process.</p><p>The Morita-Baylis-Hillman (MBH) …

Rhodium-catalyzed Asymmetric Carbon-Carbon Bond Formation Leading to the Development of Rhodium/Palladium Multi-metal Catalysis
… and palladium catalysis in the development of domino reactions. The contents are divided into 4 chapters. Chapter 1 describes the rhodium-catalyzed asymmetric ring opening (ARO) of strained bicyclic alkenes using silyl enolates. The development of this method achieved a highly enantioselective …
