Diastereoselectivity

2012
This chapter addresses diastereoselectivity. It explains how to make compounds as single diastereoisomers. The chapter begins by differentiating between stereospecific and stereoselective reactions. In stereospecific reactions, the mechanism means that the stereochemistry of the starting material determines the stereochemistry of the product and there ...

Chemodivergent and Diastereoselective Synthesis of γ-Lactones and γ-Lactams: A Heterogeneous Palladium-Catalyzed Oxidative Tandem Process.

Journal of the American Chemical Society, 2018
A palladium-catalyzed oxidative tandem process of enallenols was accomplished within a homogeneous/heterogeneous catalysis manifold, setting the stage for the highly chemodivergent and diastereoselective synthesis of γ-lactones and γ-lactams under mild ...

Copper-Mediated Diastereoselective C–H Thiolation of Ferrocenes

Organometallics, 2018
The first copper-mediated diastereoselective C–H thiolation of ferrocenes has been developed. A chiral oxazoline directing group with tert-butyl substituent is essential to the high diastereoselectivity ratio and the suppression of overreaction of ...
