Abstract
The allyl ethers (Ib) - (Id), which are prepared from the alcohol (Ia), react with trimethylallylsilane (II) in the presence of trityl perchlorate as a catalyst to give the 1,5-dienes (IV) and (V).
ChemInform Abstract
The allyl ethers (Ib) - (Id), which are prepared from the alcohol (Ia), react with trimethylallylsilane (II) in the presence of trityl perchlorate as a catalyst to give the 1,5-dienes (IV) and (V). Trimethylsilyl cyanide (VI) and compounds (Ib) - (Id) produce the unsaturated nitrile (VII) analogously. The allylic ether (IX) and the acetals (VIII) and (X) react with the silanes (XI) - (XIII) in thesame manner, forming the corresponding substitution products. Further transformations in this series are described in the original paper.
