1. ChemInform Abstract: The Unsymmetrical Silaketal as a Neutral, Removable Tether for Effecting Intramolecular Diels-Alder Reactions

Author

Michael Tjepkema, Rejean Fortin, Michael A. Bernstein, Erich L. Grimm, Robert Glaser, Michel Maillard, and John W. Gillard

Subjects
Chemistry, Intramolecular force, Polymer chemistry, Diels alder, Regioselectivity, General Medicine, Photochemistry
Abstract

Silaketals, in which reactive dienes and dienophiles are linked, can participate in intramolecular Diels-Alder reactions to produce products with a high degree of stereocontrol and with regiochemistry opposite to that predicted by bond polarization models.

2. ChemInform Abstract: A Straightforward Approach to the Synthesis of the Tricyclic Core of Taxol

Author

Michael A. Bernstein, Helene Perrier, Richard G. Ball, Scott E. Warder, Zhaoyin Wang, and Erich L. Grimm

Subjects

Abstract

The tricyclic skeleton of taxol has been synthesized. The most challenging eight-membered ring was constructed through an intramolecular nucleophilic allylic bromide-aldehyde addition reaction promoted by Zn-Cu couple
