A novel and efficient approach towards the synthesis of polysubstituted diphenylalkane derivatives have been demonstrated using a strategic combination of [2+2+2] cyclotrimerization, ethylene cross-enyne metathesis and Diels–Alder reaction as key steps. The strategy involves the stepwise functionalization of acetylenic termini of α,ω-diyne scaffold to build functionalized aromatic units.(© Wiley-VCH
使用 [2+2+2] 环三聚、乙烯交叉烯炔复分解和 Diels-Alder 反应的战略组合作为关键步骤,已经证明了一种合成多取代二苯基烷烃衍生物的新型有效方法。该策略涉及逐步功能化 α,ω-二炔骨架的炔末端以构建功能化芳族单元。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
