[New amphiphilic chlorins in the chlorophyll a series].
We treated with nucleophiles derivatives of chlorophyll a with additional six-membered cycles: delta-lactone at pyrrole D and anhydride at pyrrole C bearing a gamma-meso-bridge. In the first case, this led to the formation of substituted amides at the propionic acid residue and the introduction of hydroxy group at position 18 of the macrocycle, and, in the second case, to N-substituted cycloimides of chlorin p6.
