要旨

Peridinin is a light-harvesting carotenoid found in oceanic photosynthetic organisms. It possesses a unique γ-ylidenbutenolide function and engages in energy transfer to chlorophyll a with very high (>90%) efficiency. In order to examine the relationship between the unique structure of peridinin and its facility in carrying out energy transfer, we have synthesized two different ylidenbutenolide-modified derivatives of peridinin. In this communication, the details of the syntheses are described as are the stereochemical and spectral characteristics of the derivatives; the novel ylidenbutenolide functional group stabilizes the molecule and maintains the conjugated π-electron system in an all-trans configuration.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
