A new approach for the construction of the hydrindane framework has been achieved by intramolecular 1, 6-conjugate addition under some basic conditions. The precursors, α, β, γ, δ-unsaturated esters (11a-11d) were synthesized from the ester 8 and acrolein derivatives (6a-6d) via aldol condensation. This methodology was applied to the total synthesis of (±)-coronafacic acid and its analogues.
在某些基本条件下,通过分子内1、6-共轭物的添加,已经获得了一种新的构造氢化茚骨架的方法。通过醛醇缩合从酯8和丙烯醛衍生物(6a-6d)合成前体α,β,γ,δ-不饱和酯(11a-11d)。该方法学应用于(±)-coronafacic acid及其类似物的全合成。
