【摘要】：正J.Am.Chem.Soc.2017,139,3631~3634不對稱烯丙基化反應是構(gòu)建立體選擇性C—C鍵的重要策略之一,傳統(tǒng)烯丙基化反應中由于離去基團的存在導致反應的原子經(jīng)濟性不高.聯(lián)烯的加成反應可實現(xiàn)100%原子經(jīng)濟性的不對稱烯丙基化反應.選擇性地對聯(lián)烯端位加成是不對稱催化領(lǐng)域的挑戰(zhàn)性課題.目前報道的策略大都是得到支鏈加成的烯丙基化產(chǎn)物,而且對映選擇性較低,
[Abstract]:Asymmetric allylation is one of the most important strategies for constructing stereoselective C-C bond. In the conventional allylation reaction, the atom economy of the reaction is not high due to the presence of the leaving group in the conventional allylation reaction, I. e., the asymmetric allylation reaction of J.Am.Chem.Soc.2017139C3631C3634 is one of the important strategies for the construction of stereoselective C-C bond. The addition reaction of diene can realize the asymmetric allylation of 100% atom economy. Selective addition of end site to enene is a challenging subject in asymmetric catalysis field. At present, most of the reported strategies are to obtain allylation products with branched chain addition, and the enantioselectivity is low.
