An intramolecular FeCl3-catalyzed Michael addition reaction of styrene, a poor nucleophile, onto α,β-unsaturated ketones was developed for the synthesis of highly substituted indene derivatives. The method was further applied to the total synthesis of the sesquiterpene natural products (±)-jungianol and 1-epi-jungianol.
为了合成高度取代的茚衍生物,开发了分子内FeCl 3催化的,亲核性较差的苯乙烯的迈克尔迈克尔加成反应到α,β-不饱和酮上。该方法进一步施加到倍半萜烯天然产物(±)-jungianol和1-全合成外延-jungianol。
