Abstract:
β-halogenated enol esters and ethers are versatile building blocks in organic synthesis, which has attracted increasing attention. In this study, we report the facile trans-oxyiodination and oxychlorination of alkynes, leading to the direct construction of versatile halogenated enol esters and ethers. This transformation features an easy operation, optimal atomic economy, a strong functional group tolerance, broad substrate scope, and excellent trans-selectivity. Employing highly electrophilic bifunctional N–X (halogen) reagents was the key to achieving broad reaction generality. To our knowle

Abstract:
The α-halo-β-ketosulfonyl functionality was attacked by ethanethiolate at the halogen which, in the presence of a proton source, usually resulted in reduction to the β-ketosulfone. A range of other soft nucleophiles did not react, whereas hard nucleophiles invariably attacked at the carbonyl, with subsequent cleavage to α-halosulfones. Ambident arylsulfinate anions usually attacked at halogen to form the sulfonyl halide, which reacted with excess sulfinate to give an intermediate that is readily attacked by alcohols. This reaction resulted in the formation of alkyl arylsulfinate esters in reas

Abstract:
A simple gram-scale method for the preparation of esters and dialkylamides of 2-(fluoro/iodo)-2H-azirine-2-carboxylic acids via the halogen exchange (Halex) reaction of 2-bromo-substituted analogues is reported. The method operates with inexpensive and safe reagents­, Bu4NF and potassium iodide, providing high product yields. Alternatively, 2-fluoro-2H-azirine-2-carboxylates can be prepared from 2-iodo- and 2-chloro-analogues. The latter compounds can be obtained in practically quantitative yield by treating the 2-iodo- and 2-bromo-2H-azirine-2-carboxylic esters with Bu4NCl.
