    • The typical procedure of thermolysis is as follows: a solution of 6 (0.255 g, 0.88 mmol) in 10 mL of o-xylene was stirred under argon at 130°C for 3 h. After cooling, the solvent was removed under pressure (1 mmHg). The resulting oil was purified by flash chromatography on silica gel (petroleum ether-diethyl ether 2:8) to afford compound 7a (0.175 g, 68%) and compound 7b (0.036 g, 14%).
