An efficient Pd(0)-catalyzed deacylative allylation (DaA) of enolcarbonates (as pro-nucleophile) of cycloalkanones sharing acyl functionality at C2-position with readily available allylic alcohols (as pro-electrophiles) is disclosed under mild reaction conditions. A wide variety of cycloalkanones with an aromatic ring and allyl group at C-2 position (all-carbon quaternary center) are obtained in good to excellent yields (36 examples). The usefulness of this methodology has been shown by a total synthesis of Amaryllidaceae alkaloid, (±)-crinane from 2-aryl cyclohexanone in 5 steps.

烯醇碳酸盐的催化脱酰基烷基化（DaA）：（±）-三氢呋喃的全合成

在温和的反应条件下，公开了一种有效的Pd（0）催化的环烷酮的烯醇碳酸酯（作为亲核体）的Pd（0）催化脱酰基烯丙基化（DaA），该环烷酮在C 2位与容易获得的烯丙醇（作为亲电子体）共享酰基功能。获得了各种具有良好至极好的收率的，具有在C-2位置（全碳季中心）的芳环和烯丙基的环烷酮（36个实例）。该方法的有用性已由5个步骤由2-芳基环己酮全合成金莲花科生物碱，（±）-肉桂烷。
