Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 21436-03-3, C6H14N2. A document type is Article, introducing its new discovery.
An organocatalyzed endo [4+2] cycloaddition between enones as pro-diene and allylidene malononitrile as dienophile leading to cyclohexanones with two 1,3-related stereogenic centres and an all-carbon quaternary centre has been developed. The reactions were performed under ?green reaction? conditions using water as the reaction medium and ambient conditions. When allylidene cyanoacetate was used as the dienophile, cyclohexanones with three contiguous stereogenic centres, one of which is an all-carbon quaternary centre, were formed. The products were obtained in high yield and with acceptable diastereo- and enantioselectivity.
