An efficient, convenient short synthetic procedure for the synthesis of the intricate 5A5B6C-ring fusion topologies of tricyclic spiranoid β-hydroxybutyrolactones through lactonization of the key intermediate trans-α-hydroxyindenones with malonates is described. All the compounds synthesized exhibited environmentally benign characteristics, moderate fungicidal, nematocidal, and anti-TMV activities.

Organic & Biomolecular Chemistry

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.
