A New Ent-Kaurane from the Roots of Lasianthaea aurea

A known kaurenoic acid ( 1 ), together with a new kaurane derivative named 3α-isobutyryloxykaurenoic acid ( 2 ), was isolated from the roots of Lasianthaea aurea, a plant endemic to Mexico. The compounds were characterized using their physical and spectroscopic data. In order to verify the structure...

Description
Summary:A known kaurenoic acid ( 1 ), together with a new kaurane derivative named 3α-isobutyryloxykaurenoic acid ( 2 ), was isolated from the roots of Lasianthaea aurea, a plant endemic to Mexico. The compounds were characterized using their physical and spectroscopic data. In order to verify the structure and absolute configuration of 2 , the derived methyl ester 3 , obtained after diazomethane treatment, was subjected to single-crystal X-ray diffraction analysis, whose Flack and Hooft parameter calculations evidenced that the new natural product is an ent-kaurane derivative.
