method for the selective 1,4-conjugate allylation of α,β-unsaturated aldehydes is reported. The method employs an air-stable diethanolamine-complexed boronic acid (DABO boronate) as the allyl transfer reagent and promotes conjugate addition over 1,2-addition. A variety of aryl- and alkyl-substituted enals are tolerated, providing δ,ε-unsaturated aldehyde products in good yields and selectivities under mild

Highly diastereo- and enantioselective1,3-dipolarcycloadditions between functional ketonitrones and β-substituted enals are promoted by organocatalysis with the imidazolidinium catalyst of MacMillan. Study of the scope of the reaction shows that high selectivities are conserved by varying the N-protecting group or the ester function. However it is sensitive to sterical interaction with the C-substituent
功能性酮硝酮和 β-取代烯醛之间的高度非对映选择性和对映选择性 1,3-偶极环加成通过 MacMillan 的咪唑啉鎓催化剂的有机催化作用得到促进。对反应范围的研究表明,通过改变 N-保护基团或酯官能团可以保持高选择性。然而,它对与硝酮的 C 取代基的空间相互作用很敏感。反应在所有情况下都以高外选择性进行。在大多数情况下,观察到与协同机制不相容的第三种非对映异构体,尽管数量很少。DFT 计算证明环加成以非协同方式进行,首先将硝酮加入到双键上,然后进行环化。这种机制解释了观察到的次要非对映异构体的形成。此外,该反应的非对映选择性和对映选择性显示为中间热力学控制,非对映体比例受亚胺水解动力学的调节。
