HTIB-Mediated One-Pot Synthesis of Some 2-Substituted 4-Styrylthiazoles from (E)-4-Arylbut-3-en-2-ones
摘要:
The reaction of (E)-4-arylbut-3-en-2-ones with [(hydroxy(tosyloxy)iodo]benzene (HTIB) followed by treatment with thioureas, thioamide, and thiobenzamide has offered a one-pot synthesis of 2-substituted 4-styrylthiazoles.Supplemental materials are available for this article.

On the [2+2] Cycloaddition of 2-Aminothiazoles and Dimethyl Acetylenedicarboxylate. Experimental and Computational Evidence of a Thermal Disrotatory Ring Opening of Fused Cyclobutenes
The reaction of 2-(phenylamino)- and 2-(dimethylamino)thiazoles with dimethyl acetylenedicarboxylate led unexpectedly to dimethyl 6-(phenylamino)- and 6-(dimethylamino)-3,4-pyridinedicarboxylates. Those compounds reasonably result from a sequence of reactions initiated by a [2 + 2] cycloaddition of the alkyne to the formal CC of the thiazole ring. These pyridines were obtained in nearly all the cases
