Abstract
A mixture of pheophorbide a and pyropheophorbide a was prepared by acid degradation of silkworm excrement crude chlorophylls. Pheophorbide a obtained reacted directly with amines through the cleavage of its cyclopentanone ring V without separation. 11 chlorin e6 - 6 - amides were thus synthesized.
