The cyclization of 3,4,5-trimethoxycinnamic acid ethyl ester (LI) with malonic acid ethyl ester potassium salt (LII) by means of Mn(OAc)3 gives the tetrahydrofuranone (LIII), which is acylated with 1,3-benzodioxol-5-ylcarbonyl chloride (LIV) yielding the tetrahydrofuranone (LV). Finally, this compound is rearranged and decarboxylated with SnCl4 to the target intermediate (XI).
