Synthesis of chlorins, bacteriochlorins and their tetraaza analogues

The currently known methods for the synthesis of hydrogenated derivatives of synthetic porphyrins – chlorins, bacteriochlorins, isobacteriochlorins and their tetraaza analogues – are considered. Reactions involving quasi-isolated double bonds including reduction, oxidative addition and cycloaddition are presented. Examples of direct synthesis of these macroheterocycles are given.
