Stereochemistry of Thermal Ring Opening of Substituted 7-(Ethoxycarbo-nyl)bicyclooct-1(6)-enes and Related Substances.

Thermally driven ring openings of the substituted 3-formylcyclobutenes 16 and 26 occur with exclusive inward rotation of the formyl group.Thermolysis of the ester 13 results in predominant formation of the ester diene 17 (outward rotation of CO2Et), while
