A rearrangement pathway toward the unprecedented tricyclo[4.4.0.02,8]decane skeleton is proposed. Both compounds showed antiproliferative activity when targeting HeLa, MCF-7, KB, and HT-29 cancer cell lines in the range 0.05-10 μM. © 2013 The American Chemical Society and American Society of Pharmacognosy.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyChemistryMedicinePharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1021/np4007074
