A Concise Total Synthesis of (±)- and (−)-Okilactomycin D

Autor: Thomas R. Hoye, Dawen Niu

Publikováno v: Organic Letters. 14:828-831

The spirotetronate okilactomycin D (7) has been efficiently synthesized by a route featuring a substrate-controlled, diastereoselective (8:1) intramolecular Diels-Alder (IMDA) reaction of 11. The assigned absolute configuration of (-)-7 was confirmed

Diels-Alder Cycloaddition: Fawcettimine (Williams), Apiosporic Acid (Helmchen), Marginatone (Abad- Somovilla), Okilactomycin (Hoye), Vinigrol (Barriault), Plakotenin (Bihlmeier/Klopper)

Autor: Douglass F. Taber

Publikováno v: Organic Synthesis

Highly substituted dienes and dienophiles are often reluctant participants in intermolecular Diels-Alder cycloaddition. Nevertheless, Robert M. Williams of Colorado State University, in the course of a synthesis of fawcettimine 4, was able (J. Org. C

Toward a Total Synthesis of Okilactomycin. 1. A Direct, Enantiocontrolled Route to the Western Sector

Autor: Serge L. Boulet, Leo A. Paquette

Publikováno v: Synthesis. 2002:888-894

A synthesis of the western half of the macrocyclic ring framework of the antitumor antibiotic okilactomycin is described. The strategy employed rests on an efficient synthesis of meso-2,4-dimethylglutaric anhydride and ensuing resolution via reaction

Total Synthesis of (−)-Okilactomycin

Autor: Amos B. Smith, Todd Bosanac, Kallol Basu

Publikováno v: Journal of the American Chemical Society. 129:14872-14874

A highly convergent synthesis of (-)-okilactomycin is described. Key reactions of this synthesis include a strategy-level diastereoselective oxy-Cope rearrangement/oxidation sequence, a Petasis-Ferrier union/rearrangement tactic, and an efficient RCM

Exploring Prins Strategies for the Synthesis of Okilactomycin

Autor: Daniel W. Custar, Karl A. Scheidt, William Morris, Jason M. Tenenbaum

This account describes the convergent synthesis of (−)-okilactomycin. The first-generation approach focused on the assembly of two complex fragments through a Prins reaction of a dioxinone and α-hydroxy aldehyde. While this route was not ultimatel
