Total synthesis of aspercyclides A and B via intramolecular oxidative diaryl ether formation.

Tatsuya Yoshino et al.

Organic letters, 14(16), 4290-4292 (2012-08-09)

A highly efficient total synthesis of the 11-membered cyclic aspercyclides A (1) and B (2) has been achieved by chemo- and regioselective intramolecular oxidative C-O bond formation from differently substituted diphenols.

Proceedings of the National Academy of Sciences of the United States of America, 110(43), 17189-17194 (2013-10-09)

Although metallocofactors are ubiquitous in enzyme catalysis, how metal binding specificity arises remains poorly understood, especially in the case of metals with similar primary ligand preferences such as manganese and iron. The biochemical selection of manganese over iron presents a
