Witrynathe substituent of the Michael acceptor, the ratio of C carbonyl/Cb that describes the preference of an addition to one carbon atom or to the other can signi cantly be altered. Therefore, the electronic features of a-b unsaturated Michael acceptors play aInstitute of Polymer Science and Technology, Juan de la Cierva 3, 28006, Madrid, Spain. In organic chemistry, the Michael reaction or Michael addition is a reaction between a Michael donor (an enolate or other nucleophile) and a Michael acceptor (usually an α,β-unsaturated carbonyl) to produce a Michael adduct by creating a carbon-carbon bond at the acceptor's β-carbon. It belongs to the … Zobacz więcej As originally defined by Arthur Michael, the reaction is the addition of an enolate of a ketone or aldehyde to an α,β-unsaturated carbonyl compound at the β carbon. The current definition of the Michael reaction has broadened … Zobacz więcej The research done by Arthur Michael in 1887 at Tufts University was prompted by an 1884 publication by Conrad & Kuthzeit on the reaction of ethyl 2,3-dibromopropionate … Zobacz więcej Classical examples of the Michael reaction are the reaction between diethyl malonate (Michael donor) and diethyl fumarate (Michael acceptor), that of diethyl malonate and mesityl oxide, that of diethyl malonate and methyl crotonate, that of 2-nitropropane Zobacz więcej In the reaction mechanism, there is 1 (with R an alkoxy group) as the nucleophile: Deprotonation of 1 by a base leads to carbanion 2, stabilized by its electron-withdrawing … Zobacz więcej Researchers have expanded the scope of Michael additions to include elements of chirality via asymmetric versions of the reaction. The … Zobacz więcej Pharmaceuticals A Michael reaction is used as a mechanistic step by many covalent inhibitor drugs. Cancer drugs such as ibrutinib, … Zobacz więcej how old nle choppa now
