A solid-phase synthesis that provides easy access to 2-amino-5-sulfanylthiazoles with variable substituents at C-2, C-4, and C-5 has been developed. The key step of this synthesis is a new C-sulfanylation of resin-bound 2-aminothiazoles by mixtures of various sulfur-containing building blocks and io
## Abstract New 3‐aroyl‐4‐(3‐chromonyl)‐2‐pyrazolines have been synthesized by the reaction of 3‐(3‐aryl‐3‐oxo‐propenyl)chromen‐4‐ones and diazomethane. Some of these 2‐pyrazolines have also been N‐acylated with a mixture of anhydrous pyridine and acetic anhydride or propionic anhydride. Structures
