The one-pot combination of Claisen rearrangement of allyl vinyl ethers followed by an intramolecular hydroacylation catalysed by RhCl(cod)(dppe) is used as a key step in the synthesis of meso-dimethyl-1,4-dioxa-dispiro[4.2.4.2]tetradecan-10-one (12). The diastereospecific outcome of the reaction is discussed. This product is a potential precursor in the synthesis of solavetivone.
一锅结合的烯丙基乙烯基醚的克莱森重排,然后由RhCl(cod)(dppe)催化的分子内加氢酰化被用作合成内消旋-二甲基-1,4-二氧杂双螺[4.2]的关键步骤。 4.2] tetradecan-10-one(12)。讨论了反应的非对映特异性结果。该产品是Solavetivone合成中的潜在前体。
