Solvatochromism of dyes inspired in Effenberger's probe

Solvatochromic dyes have been utilized in recent decades as probes to measure the polarity of the medium. An interesting example is the Effenberger's dye (ED), which exhibits a very pronounced positive solvatochromism, being considered a dye that probes p

Mixed carboxylic-sulfonic anhydride in reaction with imines: A straightforward route to water-soluble β-lactams via a Staudinger-type reaction

The first example of employing a mixed carboxylic-sulfonic anhydride in reaction with imines is reported. Unlike its well-studied isostere homophthalic anhydride, benzo[c][1,2]oxathiin-3(4H)-one 1,1-dioxide gave no product of a formal [4 + 2] cycloaddition and only followed an alternative reaction pathway toward β-lactams, presumably, via a formal [2 + 2] cycloaddition (a Staudinger-type reaction). Optimized reaction conditions involve the use of triethylamine as a base promoter, which also allows isolating the product β-lactam benzene sulfonic acids as respective triethylammonium salts by conventional column chromatography. The reaction shows some preference to trans-isomer formation; pure diastereomers can be isolated in some cases.
