The mode of reaction of the 1,2,3,4,5,6,7-heptamethoxycarbonylcycloheptatriene with primary amines depends on the reaction conditions and leads to selective formation of N-substituted (heptamethoxycarbonyl)nortrop-2-enes and/or 3-vinylpyridin-2-ones bearing six ester groups. The influence of the solvent on the selectivity of the formation of nortropenes and pyridinones was studied.
1,2,3,4,5,6,7-七甲氧基羰基环庚三烯与伯胺的反应方式取决于反应条件,并导致选择性形成N-取代的(七甲氧基羰基)nortrop-2-enes和/或3 -带有六个酯基的-乙烯基吡啶-2-酮。研究了溶剂对降冰片烯和吡啶酮形成选择性的影响。
