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)。
