以脱镁叶绿酸-a甲酯为原料, 利用Vilsmeier反应合成δ-(甲酰乙烯基)二氢卟吩衍生物. 镍(II)脱镁叶绿酸-a甲酯和镍(II)红紫素-18与Vilsmeier试剂作用, 生成了E环被打开的镍(II) δ-(甲酰乙烯基)红紫素-7-三甲酯和镍(II) δ-(甲酰乙烯基)二氢卟吩P6三甲酯. 镍(II) N-乙酰氧基红紫素-18-酰亚胺和Vilsmeier试剂作用, 生成了镍(II) δ-(甲酰乙烯基)-N-乙酰氧基红紫素-18-酰亚胺. 当这些化合物脱去镍离子后, 吸收波长明显红移, δ-(甲酰乙烯基)-N-乙酰氧基红紫素-18-酰亚胺的吸收波长达到742 nm. 同时保留了对δ-位再进行化学修饰的可能性. 合成的新化合物均由核磁共振、红外光谱、元素分析和质谱予以证实.

Starting from methyl pheophorbide-a, the derivatives of δ-(2-formylvinyl)-chlorins were synthesized by Vilsmeier reaction. The nickel(II) methyl pheophorbide-a or nickel(II) methyl purpurin-18 reacted with 3-(dimethylamino)-acrolein/phosphoryl chloride to give nickel(II) δ-(2-formylvinyl)-purpurin-7-trimethyl ester or nickel(II) δ-(2-formylvinyl)-chlorin P6 trimethyl ester. When nickel(II) purpurin-18 imide reacted with Vilsmeier agent, the deriva-tives of nickel(II) δ-(2-formylvinyl)-purpurin-18 imide were obtained. By treatment of the deriva-tives of nickel(II) δ-(2-formylvinyl)-chlorin with trifluoroacetic acid, the removal of central nickel(II) ion was accomplished. The derivatives of δ-(2-formylvinyl)-chlorin demonstrated a con-siderable bathochromic shift of the major absorption band in the red region of the optical spectrum. The maximal UV/vis absorption of δ-(2-formylvinyl)-purpurin-18 imide was 742 nm. The structures of all new compounds were characterized by elemental analysis, UV, IR, MS and 1H NMR spec-tra.
