3-乙氧基环丁酮与烯丙基三烷基硅烷进行[4 + 2]环加成反应，得到3-乙氧基-5-[（三烷基硅基）甲基]环己-1-酮。使用烯丙基-叔丁基二苯基硅烷引发1，5-氢化物转移，得到2-[3-（叔丁基二苯基硅基）丙基]-6-甲基四氢-4-吡喃酮。
Formal [4 + 2] cycloaddition between various 3-ethoxycyclobutanones and allyltrialkylsilanes proceeded to give 3-ethoxy-5-[(trialkylsilyl)methyl]cyclohexan-1-ones by catalysis with tin(VI) chloride. The use of allyl-tert-butyldiphenylsilane induced 1,5-hydride transfer, which gave 2-[3-(tert-butyldiphenylsilyl)propyl]-6-methyltetrahydro-4-pyrones.
