chiral biaryls, formed in the course of the dehydro-Diels–Alder (DDA) reaction, has been disclosed. It is based on asymmetric induction of the newly formed chirality axis by a chirality center, which is present in the two synthesized DDA reactants. Depending on the different length of the linkers joining the alkyne moieties the DDA reaction may be triggered photochemically or thermally, where only the thermal
已经公开了在脱水-狄尔斯-阿尔德(DDA)反应过程中形成的轴向手性联芳基的立体选择性合成的新概念。它基于两个合成的DDA反应物中存在的手性中心对新形成的手性轴的不对称诱导。取决于连接炔基部分的接头的不同长度,DDA反应可以光化学或热引发,其中仅热变体是立体选择性的。
