Abstract

Using proton n.m.r. spectroscopy, reversed-phase h.p.l.c., and synthetic interconversion into methyl bacteriopheophorbides-c (3), the chirality of the 2-(1-hydroxyethyl) in methyl bacteriopheophorbides-e (and hence the bacteriochlorophylls-e) from Chlorobium phaeobacteroides is shown to be 95% (R) and 5% (S) for the [4-Et,5-Et] homologue, 40% (R) and 60% (S) for the [Pr n,Et] compound, and approximately 1% (R) and 99% (S) for the [Bu i,Et] homologue.
