Abstract

The first total synthesis of racemic chondrosterin I was accomplished. The synthetic features include a Michael addition to incorporate a nitro alkane moiety, an oxidative Nef reaction, intramolecular cyclization of the γ-ketoester derivative, and a desymmetric intramolecular aldol reaction of the meso diketoester compound. The present strategy will be applicable to the synthesis of an optically active form by asymmetric desymmetrization.

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.
