Polycyclic Spiro Lignans and Biphenyl Tetrahydrofuranone Lignans from Gymnotheca involucrata

Planta Medica, 2016
Four rare polycyclic spiro lignans (1-4) and four new biphenyl tetrahydrofuranone lignans (5-8) were isolated from the whole plant of Gymnotheca involucrata. The structures of the new compounds were elucidated on the basis of detailed spectroscopic analysis and the absolute configuration of 1 was confirmed by single crystal X-ray diffraction.

Biosynthetic relationship of aryltetralin lactone lignans to dibenzylbutyrolactone lignans

Phytochemistry, 1986
Abstract Feeding experiments in Podophyllum hexandrum plants have shown that the dibenzylbutyrolactone lignan yatein is a satisfactory precursor of the aryltetralin lignan podophyllotoxin. The corresponding cis isomer of yatein was also incorporated, but to a lesser extent, and probably via yatein.
