Do aziridines require Lewis acids for cleavage with ionic nucleophiles
TL;DR: In this article, a variety of activated aziridines were cleaved by sodium azide and sodium cyanide in aqueous acetonitrile at reflux, in the absence of any Lewis acid, to provide ring-opened products in quantitative yields.
Journal ArticleDOI
Organocatalytic enantio- and diastereoselective synthesis of highly substituted δ-lactones via a Michael-cyclization cascade
TL;DR: An organocatalyzed Michael-cyclization cascade approach of readily available α,β-unsaturated aldehydes and pyrazoleamides has been developed to get highly substituted δ-lactones in excellent enantioselectivities and diastereoselectivity.
Journal ArticleDOI
Studies in the rearrangement of epoxides with lithium dialkylamide-lithium tert-butoxide
TL;DR: In this article, a rearrangement of epoxides with lithium diethylamide or lithium disopropylamide in conjunction with lithium t-butoxide was studied in different solvents.
Journal ArticleDOI
Asymmetric Multifunctional Modular Organocatalysis: One-Pot Direct Strategy to Enantiopure α,β-Disubstituted γ-Butyrolactones.
TL;DR: A simple and efficient approach to enantioenriched α,β-disubstituted γ-butyrolactones has been developed through multifunctional modular organocatalysis in a highly enantioselective and diastereoselectives manner following a one-pot sequential Michael-hemiacetalization-oxidation reaction.
Journal ArticleDOI
