Palladium-catalyzed intramolecular carbonyl allylation with SnCl2 by 5-substituted 4-methylene-5-(2-tetrahydropranyloxy)pentanals, prepared by Claisen rearrangement of 2-[1-(2-tetrahydropyranyloxy)alkyl]allyl vinyl ethers, occurred radioselectively at ambient temperature in DMI/H2O to give 2-substituted 3-methylenecyclopentanols in good yields.
通过2- [1-(2-(4-四氢吡喃氧基)烷基]烯丙基乙烯基醚的克莱森重排制备的5-取代的4-亚甲基-5-(2-四氢戊氧基)戊醛与SnCl 2进行钯催化的分子内羰基烯丙基化反应,于在DMI / H 2 O中的室温下以良好的产率得到2-取代的3-亚甲基环戊醇。
