A stereoselective thiocyanate conjugate addition to electron deficient alkynes and concomitant cyclization to N, S-heterocycles
A regio- and stereoselective thiocyanate addition to ynones is achieved using KSCN in AcOH at 70 degrees C. The reaction is extendable to ynals, ynesulfones, ynoic acids and ynoates. Adducts from ynones were readily transformed into thiazine-2-thione derivatives under slightly modified reaction conditions. In contrast, thiocyanated adducts from ynamides underwent an in situ decyanative amido cyclization towards isothiazolones. None of these events needed any transition metal or catalyst, attaining a high synthetic value.
The proportionality constant is the rate constant for the particular unimolecular reaction. You can get involved in discussing the latest developments in this exciting area about 82911-69-1. Quality Control of N-(9-Fluorenylmethoxycarbonyloxy)succinimide.
