✦ Synopsis

Zinc 3-acetyl-131-hydroxychlorin Zn-4 was efficiently prepared as a model for naturally occurring bacteriochlorophyil-d possessing 3t-hydroxyl and 13-keto groups. Synthetic model Zn-4 self-aggregates to form oligomers in non-polar organic solvents as well as the isomeric zinc 31-hydroxy -13~-oxochlorin Zn-l. Both the in-vitro aggregates are similar with the in.vivo aggregates of bacteriochlorophyll-d in the main light-harvesting antennae of photosynthetic green bacteria.
