allylic silanes bearing additional functionality in the form of either a bromide or a phenylsulphonyl group were synthesised and condensed with a variety of electrophilic partners. Subsequent cyclisation of some of the products was then possible by utilising the acid-promoted reactions of the allylsilane grouping, to give one spiropentannulated product (8) and two medium ring ether sulphones (12) and
合成了两种带有
溴或苯基磺酰基形式的具有附加官能度的烯丙基
硅烷,并与各种亲电子分子进行缩合。然后,通过利用烯丙基
硅烷基团的酸促进的反应,可以随后对某些产物进行环化,从而得到一种螺环鞣化产物(8)和两种中
环醚砜(12)和(13)。
