以醛和α-酮酯为酰基源,通过未充分利用的酰基自由基插入合成了多种蝶呤分子。这些反应给出了7-异构体的完全区域特异性,反应时间以分钟计,通常具有瞬时产物沉淀。这种方法导致通过传统的Friedel-Crafts酰化无法获得的新的蝶呤类似物的构建。通过NMR光谱和高分辨率质谱对化合物进行了表征。
A variety of pterin molecules were synthesized via an under-utilized acyl radical insertion, using aldehydes and α-keto esters as the acyl source. These reactions gave complete regiospecificity for the 7-isomer, with reaction times ranging in minutes, often with instantaneous product precipitation. This approach led to the construction of new pterin analogs unaccessable via traditional Friedel-Crafts acylation. The compounds were characterized by NMR spectroscopy and high-resolution mass spectroscopy.
