Synthesis of 5-arylated N-arylthiazole-2-amines as potential skeletal muscle cell differentiation promoters
摘要:
A series of N-arylthiazole-2-amines was prepared and their biological activity for the promotion of skeletal muscle cell differentiation was investigated, a process of significant importance in muscle regeneration. A versatile new synthetic route towards the target compounds was developed and the substrate scope of this methodology was investigated. Introduction of the 2-aminoaryl substituent was carried out via nucleophilic substitution reactions in excellent yields. Furthermore, the aryl in 5-position was introduced applying a direct arylation reaction, a major improvement compared to reported synthetic routes regarding atom efficiency and sustainability.

A method for the Pd-catalyzed coupling of 2-aminothiazole derivatives with aryl bromides and triflates is described. Significantly, for this class of nucleophiles, the coupling exhibits a broad substrate scope and proceeds with a reasonable catalyst loading. Furthermore, an interesting effect of acetic acid as an additive is uncovered that facilitates catalyst activation.
