We describe a new total synthesis of 2-styrylbenzoic acids by Heck coupling of methyl o-iodobenzoates to styrenes. Additionally, in the first general synthesis of naphtho[2,1-f]isoquinolines, these acids were transformed into phenanthrenoic acids and thence into the target compounds by a six-step sequence including a Bischler–Napieralski cyclization.
我们描述了一种新的2-苯乙烯基苯甲酸的全合成,其是将邻碘苯甲酸甲酯与苯乙烯进行Heck偶联。此外,在萘并[2,1- f ]异喹啉的第一个常规合成中,这些酸被转化为菲烯酸,然后通过包括Bischler-Napieralski环化在内的六步法转化为目标化合物。
