Chirality wiley center
WebCis and trans double bonds are sterogenic centers in that two different compounds are possible that are stereoisomers (diasteromers). However, that is not sufficient. You must have two cumulated alkenes (c=c bonds next to each other) with at least 2 substituents to have "axial" chirality. There is also helical chirality. WebFeb 27, 2024 · The results highlight the value of vinyl triflones for the stereoselective synthesis of chiral triflones and, thus, pave the way for expanding their scope of applications. The findings also open exciting prospects for streamlined access to chiral compounds with stereogenic centers in 1,3-positions from α-substituted Michael acceptors.
