Efficient Amination of Sulfides with a Ketomalonate‐Derived Oxaziridine: Application to [2,3]‐Sigmatropic Rearrangements of Allylic Sulfimides.
Alan Armstrong,Richard S. Cooke +1 more
TL;DR: In this paper, a novel N-Boc-oxaziridine derived from diethyl ketomalonate is reported, which effects efficient amination of sulfides to sulfimides.
Journal ArticleDOI
Amine‐Catalyzed Epoxidation of Alkenes: A New Mechanism for the Activation of Oxone
Journal ArticleDOI
New Methods and Synthetic Applications of Asymmetric Nitrogen Transfer
Alan Armstrong,Ian D. Edmonds,Richard S. Cooke,Stephen E. Shanahan,Jamie D. Knight,Graham R. Cumming +5 more
TL;DR: In this paper, the structure/reactivity relationships of N-alkoxycarbonyl- and N-carboxamidooxaziridines are explored, and conditions are discovered for the efficient amination of sulfides and primary amines.
Journal ArticleDOI
Oxidative Rearrangement of 2‐Alkoxy‐3,4‐dihydro‐2H‐pyrans: Stereocontrolled Synthesis of 4,5‐cis‐Disubstituted Tetrahydrofuranones Including Whisky and Cognac Lactones and Crobarbatic Acid.
TL;DR: In this paper, Jones oxidation was applied to the synthesis of the whisky lactone 9, cognac lactone 10 and crobarbatic acid 17, and the method was used to synthesize the whisky and cognac lactone.
