Visible-Light-Driven Unsymmetric gem-Difunctionalization of Vinyl Azides with Thiosulfonates or Selenosulfonates.

Organic Letters
Thiosulfonylation and selenosulfonylation of vinyl azides with thiosulfonates and selenosulfonates were achieved using Cu(dap)2Cl as a photosensitizer under visible-light irradiation. This reaction is the application of a vinyl azide substrate in a group

Isomerisation of Vinyl Sulfones for the Stereoselective Synthesis of Vinyl Azides

European Journal of Organic Chemistry, 2020
Reported is the construction, and facile base‐mediated conversation of ten differently substituted 3‐azido E‐vinyl sulfones (γ‐azido‐α,β‐unsaturated sulfones) into their isomeric vinyl azide counterparts. The requisite 3‐azido E‐vinyl sulfones were prepared from 3‐bromo E‐vinyl sulfones, which in turn were accessed from allyl sulfones via a bromination‐

Modular Synthesis of Azidobicyclo[2.1.1]hexanes via (3 + 2) Annulation of α-Substituted Vinyl Azides and Bicyclo[1.1.0]butanes.

Journal of Organic Chemistry
Here, we present a mild and rapid method to access azidobicyclo[2.1.1]hexanes via formal (3 + 2) cycloaddition of α-substituted vinyl azides and bicyclo[1.1.0]butanes under Lewis acid catalysis.

Visible-Light-Triggered Synthesis of N-α-Ketoacylated Sulfoximines by Denitrogenative and Oxidative Functionalization of Vinyl Azides.

Journal of Organic Chemistry
We have introduced a sulfoximidation reaction initiated by visible light between α-phenyl vinyl azides and NH-sulfoximines. The cost-effective and readily accessible hypervalent iodine reagent (PIDA) easily promoted the oxidative sulfoximidation process ...

S-Triggered Schmidt-type Rearrangement of Vinyl Azides to Access N-Aryl-(trifluoromethylsulfinyl)acetamides

Organic Chemistry Frontiers, 2022
A novel S-induced Schmidt-type rearrangement of vinyl azides with CF3SO2Na is reported, which is mediated by triphosgene (BTC) under mild reaction conditions.

[3 + 2] Annulation of Vinyl Azides with Aldehydes for the Synthesis of 3-Oxazolines via the [CO + CCN] Strategy.

Organic Letters
Despite the widespread utilizable value of 3-oxazolines, mild and efficient access to such a class of unique structures still remains, to date, a challenge. Herein, we present a [3 + 2] annulation strategy, guided by the retrosynthetic principle of [CO +
