Pharmaceuticals A Michael reaction is used as a mechanistic step by many covalent inhibitor drugs. Cancer drugs such as ibrutinib, osimertinib, and rociletinib have an acrylamide functional group as a Michael acceptor. The Michael acceptor on the drug reacts with a Michael acceptor in the active site of an enzyme. This … Visa mer 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 … Visa mer 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, … Visa mer Researchers have expanded the scope of Michael additions to include elements of chirality via asymmetric versions of the reaction.
