Interlocked and Knotted Rings in Biology and Chemistry
1991Catenanes are chemical entities consisting of two or more interlocked rings. Such systems, as well as knotted molecules, belong to a branch of chemistry which is related to mathematics, molecular biology and graphic art. Many endeavours have been made to build such topologicaly novel compounds.

Chemistry of the Condensed Tannin B-ring
1989The chemistry of the condensed tannin B-ring is closely related to that of the parent phenols — phenol, catechol, and pyrogallol. Many of the same reactions observed for the simple phenols can be reproduced on the tannin B-ring. These include esterification, etherification, and electrophilic addition for all the types, and metal chelation, oxidation ...
