A cooperative base system has been developed for the novel three component bis-heterocyclization of methylketoxime acetates. In a reaction complementary to previous thiazole and benzo[4,5]thieno[3,2-d]thiazole formation, the present protocol provides

Herein, iodide-catalyzed aerobic synthesis of 1,4-benzothiazines via functionalization of multiple C-H bonds with elemental sulfur is described. Beyond the well-established thiazole formation from elemental sulfur, this method provides the first acce

The synthesis of thiazoles and thiophenes starting from nitriles, via a modified Gewald reaction has been studied for a number of different substrates. 1,4-Dithiane-2,5-diol was used as the aldehyde precursor to give either 2-substituted thiazoles or

A concise asymmetric synthesis of the C1–C12 fragment of the antibacterial natural product thuggacins has been achieved. The stereochemistry of this fragment was established efficiently via stereoselective reduction and Evans-aldol condensation. Ha

The traceless cleavage of Rink amide resin to form thiazoles has been achieved using commercially available reagents. Conversion of Rink amide species to thioamides by use of Lawesson’s reagent prepares the resin bound substrates for traceless clea
