Easy way to ene‐1,1‐diamines: 1‐Haloalkynes react with secondary aliphatic amines to selectively give ene‐1,1‐diamines under the reported protocol. Single‐crystal X‐ray diffraction analysis of one of the products and its corresponding protonated form – amidinium salt – reveals structural changes occurring upon protonation of those carbon bases.
The synthesis of heterocycles relies heavily on diverse sigmatropic rearrangements triggered by the cleavage of X–Y (X, Y = C, O, N, S, I) bonds. However, a unified rearrangement approach for constructing heterocyclic libraries is highly desirable. Encouraged by computational analysis of [3,3]-sigmatropic rearrangements, we can now rapidly synthesize oxa-heterocycles by treating N-phenoxyacetamides
Desymmetrization of meso 7-aza-2,3-bis(phenylsulfonyl) bicyclo[2.2.1]hept-2-ene: a re-examination. Kinetic resolution of racemic 3-arylsulfonyl-7-aza-2-bromobicyclo[2.2.1]hepta-2,5-dienes

The inexpensive large scale preparation of N-methoxycarbonyl-7-aza-2,3-bis(phenylsulfonyl)bicyclo[2.2.1]hept-2-ene and the re-examination of its stereoselective desymmetrization are reported. Moreover, the kinetic resolution of N-protected 3-arylsulfonyl-7-aza-2-bromobicyclo[2.2.1]hepta-2,5-dienes promoted by (R,R)-hydrobenzoin is described, representing a new tool to fix the absolute stereochemistry
