## Abstract Assignment of all ^13^C chemical shifts of perezone (1) and some derivatives was possible using time averaged 25·15 MHz spectra with the aid of proton noise modulated and CW decoupling. Rapid interconversion of tautomeric forms of 2,5‐dihydroxy‐1,4‐benzoquinones is deduced from the ^13^
A combination of NMR experiments, including I3C and "N DEPT, COSY, NOESY, HMQC and HMBC experiments, was used to assign the structures and stereochemistries of two isomeric bicyclo 12.2.21 octenedione derivatives produced by the reaction of perezone with thiourea, followed by treatment with silica g
