Benzalacetone-Based β-Isothiocyanatoketones: Synthesis and Transformation to Diaryl-Substituted 14-Membered Cyclic Thiosemicarbazones and Related Heterocycles
A synthesis of novel 4-aryl-4-isothiocyanatobutan-2-ones based on addition of thiocyanic acid to benzalacetones has been developed. The prepared isothiocyanates react with equim...
