The annelated tetrahydrofuran derivatives 14 and 15, resp., are formed in moderate yield by intramolecular trapping reaction of the carbonyl ylide intermediates 9, which are generated either by thermal ring opening of the trans-stilbene oxides 7t/8t or by photolysis of the cis-isomers 7c/8c.
分别通过反式二苯乙烯氧化物7t / 8t的热环开环或顺式的光解产生的羰基内酯中间体9的分子内捕获反应,以中等收率形成了退火的四氢呋喃衍生物14和15。 -异构体7c / 8c。
