Resumen
Two novel polyprenylated phloroglucinol derivatives were isolated from the trunk of Kielmeyera lathrophyton (Clusiaceae). Lathrophytoic acid A presented an unusual caged carbon skeleton with a 1,3-dione-4-cyclopentanol moiety. Lathrophytoic acid B exhibited a highly substituted bicycle[3.3.1]non-ane skeleton and an isopropylfuran system which was formed by unusual cyclization of a prenyloxy side
chain.
