New Lobane and Cembrane Diterpenes from Two Comorian Soft Corals
Preliminary biological investigation of a collection of Comorian soft corals resulted in the selection of two specimens, one of Sarcophyton and the other of Lobophytum, on the basis of their toxicity on larvae of the brine shrimp (Artemia salina) and ...

An Unexpected Transannular [4+2] Cycloaddition during the Total Synthesis of (+)‐Norcembrene 5
They may look alike… During studies toward the total synthesis of the norditerpene natural product norcembrene 5, one diastereomer of a key intermediate (α‐OAc at C13) underwent clean and spontaneous Diels–Alder cycloaddition at room temperature (see scheme).

EBC‐342: A Novel Tetrahydrofuran Moiety Containing Casbane from the Australian Rainforest
Although well known, the casbane family of natural products are not often isolated from either terrestrial or marine environments. The Australian Rainforest plant Croton insularis has provided a number of interesting casbanes, of which EBC‐342 described herein, is the first to contain a tetrahydrofuran ring.
