δ-Thiolactones as Prodrugs of Thiol-Based Glutamate Carboxypeptidase II (GCPII) Inhibitors

Dana Ferraris, +11 more
- 09 Jan 2014 - 
TL;DR: Thiolactones derived from thiol-based glutamate carboxypeptidase II inhibitors exhibited efficacy in a rat model of neuropathic pain following oral administration, consistent with the oral plasma pharmacokinetics.

Switching the reactivity of dihydrothiopyran-4-one with aldehydes by aqueous organocatalysis: Baylis-Hillman, aldol, or aldol condensation reactions.

M. Saeed Abaee, +6 more
- 07 Sep 2011 - 
TL;DR: An aqueous medium containing catalytic amounts of a tertiary amine was employed to direct the chemoselectivity of the reaction of aldehydes with 1a to form syn/anti mixtures of 3 with the syn isomers being the major products.
