Allylsilanes containing heteroatom nucleophiles yield cyclic products when treated with (NH4)2Ce(NO3)6. For example, hydroxy and amido-containing allylsilanes yield the corresponding tetrahydrofuran, tetrahydropyran, and piperidine analogs. These reactions and their application to natural product synthesis will be discussed.
当用(NH 4)2 Ce(NO 3)6处理时,含有杂原子亲核试剂的烯丙基
硅烷会产生环状产物。例如,含羟基和含酰胺基的烯丙基
硅烷可产生相应的
四氢呋喃,
