Journal ArticleDOI
Syntheses of Chiral β- and γ-Amino Ethers, Morpholines, and Their Homologues via Nucleophilic Ring-Opening of Chiral Activated Aziridines and Azetidines
TL;DR: Lewis acid catalyzed quaternary ammonium salt mediated highly regioselective ring-opening of chiral activated aziridines and azetidines with alcohols to nonracemic β- and γ-amino ethers has been developed and synthesized morpholines and their homologues with high enantiospecificity.
Journal ArticleDOI
Syntheses of Imidazo-, Oxa-, and Thiazepine Ring Systems via Ring-Opening of Aziridines/Cu-Catalyzed C–N/C–C Bond Formation
TL;DR: A simple and unpredicted synthetic pathway toward racemic and scalemic tetrahydrodibenzoimidazoazepines has been invented serendipitously proceeding through an S(N)2-type ring-opening of N-activated aziridines with 2-bromobenzylamine followed by a hitherto unprecedented cascade cyclization reaction sequence.
Journal ArticleDOI
A Stereoselective Route to Tetrahydrobenzoxazepines and Tetrahydrobenzodiazepines via Ring-Opening and Aza-Michael Addition of Activated Aziridines with 2-Hydroxyphenyl and 2-Aminophenyl Acrylates
TL;DR: A simple and efficient synthetic route to 2,3,4,5-tetrahydrobenzoxazepines and -benzodiazepines bearing easily functionalizable appendages is developed by ring-opening of activated aziridines with 2-hydroxyphenyl acrylates and 2-aminophenyl acRYlate and subsequent intramolecular C-N bond formation through palladium-catalyzed aza-Michael reaction.
Journal ArticleDOI
Stereospecific Synthesis of 2-Iminothiazolidines via Domino Ring-Opening Cyclization of Activated Aziridines with Aryl- and Alkyl Isothiocyanates.
TL;DR: Lewis acid catalyzed domino ring-opening cyclization of activated aziridines with aryl and alkyl isothiocyanates has been accomplished leading to the formation of a wide variety of highly substituted and functionalized 2-iminothiazolidines with excellent diastereo- and enantiospecificity.
Journal ArticleDOI
Stereospecific Synthesis of 1,4,5,6-Tetrahydropyrimidines via Domino Ring-Opening Cyclization of Activated Aziridines with α-Acidic Isocyanides
TL;DR: An expeditious synthetic route to access structurally diverse 1,4,5,6-tetrahydropyrimidines via domino ring-opening cyclization of activated aziridines with α-acidic isocyanides has been established.
