A strapped chiroporphyrin free base with two 8-methylene
chains linking two adjacent meso-substituents was synthesized as the
α4 conformer; insertion of Ni(II) triggered a
complete conversion to the αβαβ complex, and
demetallation totally regenerated the strapped free base in the
α4 conformation.
合成了一种带有两个8-亚甲基链连接相邻次甲基取代基的束缚型
卟啉自由碱,形成α4构象;插入Ni(II)引发了完全转变为αβαβ复合物的过程,而脱
金属反应则完全再生了处于α4构象的束缚型自由碱。
