Sequentielle Transformationen in der Organischen Chemie eine Synthesestrategie mit Zukunft
Lutz F. Tietze,Uwe Beifuss +1 more
TL;DR: The organisch-chemische Synthese hat stets eine grose Faszination auf den Chemiker ausgeubt, und sie wird auch in Zukunft nichts von ihrer Bedeutung verlieren as discussed by the authors.

Hetero diels-alder reactions in organic chemistry
Lutz F. Tietze,Georg Kettschau +1 more
TL;DR: In this article, an overview is given for the period since 1989 describing the reaction of heterobutadienes and other dienophiles such as carbonyls, thiocarbonyls and iminium salts.

Asymmetric domino reactions. Part A: Reactions based on the use of chiral auxiliaries
TL;DR: Asymmetric domino reactions are reviewed for the first time in this article, covering the classification and characteristics of these reactions together with the most important applications, showing that the concept of asymmetric Domino reactions has emerged as a powerful tool in asymmetric synthetic chemistry.

1.11 – The Knoevenagel Reaction
Lutz F. Tietze,Uwe Beifuss +1 more
TL;DR: For example, Knoevenagel et al. as mentioned in this paper showed that the reaction of benzaldehyde and ethyl acetoacetate in the presence of piperidine gives the bis adduct at room temperature and at 0°C the benzylidene-1,3-di- carbonyl.

Basic Principles of the CIP-System and Proposals for a Revision†
Vladlmir Prelog,Günter Helmchen +1 more
TL;DR: From Configurational Notation of Stereoisomers to the Conceptual Basis of Stereo Chemistry as mentioned in this paper is the title of a lecture [V. Prelog, ACS Symp. Ser. No. 12 (1975) 179] in which the chronologically and alphabetically third member of the CIP-triumvirate discusses the history of the system.
Journal ArticleDOI
The Ene Reaction
TL;DR: The ene reaction is defined as the indirect substituting addition of a compound with a double bond (enophile) to an olefin with an allylic hydrogen (ene) as discussed by the authors.
Journal ArticleDOI
Intramolecular Ene Reactions in Organic Synthesis
TL;DR: In this article, a variety of substituted, fused and bridged ring systems, including natural products, are discussed systematically illustrating the possibilities, limitations, and common features of this cyclization reaction and its reverse ring-opening process.

The Unambiguous Specification of the Steric Course of Asymmetric Syntheses
Dieter Seebach,Vladimir Prelog +1 more
TL;DR: In this article, the relative topicity of approach of reactants is defined as like {Ik} and unlike (ul) if the corresponding descriptor pairs are Re*,Re*. or R*,Re*, and Re*,Si* or R*)Si*, respectively.
