Pheophorbide b ethyl ester from a chlorella vulgaris dietary supplement.


ABSTRACT: In the title compound, C(37)H(38)N(4)O(6), four five-membered nitro-gen-bearing rings are nearly coplanar. Two N atoms in two these five-membered rings have attached H atoms, which contribute to the formation of intra-molecular N-H?N hydrogen bonds [N?N = 2.713?(5)-3.033?(6)?Å].
