Five alkynyl pyridines were prepared and cyclized to naphthylpyridines as the main products in the course of a Photo-Dehydro-Diels-Alder reaction. Four of the final products are axially chiral and the determination of the rotational barrier by DFT calculations, dynamic NMR and HPLC experiments is demonstrated.
制备了五个炔基吡啶,并在光-脱氢-狄尔斯-阿尔德反应过程中环化成萘啶作为主要产物。最终产品中有四个是轴向手性的,并且通过DFT计算,动态NMR和HPLC实验证明了旋转势垒的确定。
