NaOH ethanol HO This reaction involves an intramolecular Michael reaction followed by an intramolecular aldol reaction. The steps involved are as follows: 1. Deprotonation to form enolate ion 1; 2. Cyclization via an intramolecular Michael reaction to form intermediate 2; 3. Deprotonation to form enolate ion 3; 4. Intramolecular aldol cyclization to form...

If the Favorskii R of 2-chlorocyclohexanone is carried out using sodium ethoxide in ethanol, the product is ethyl cyclopentanecarboxylate, shown below. CI CH,CH2O Na The reaction procceds via a 5-step mechanism and can be formulated as follows. Step 1: Formation of an enolate ion 1 and ethanol. Step 2: An intramolecular alkylation reaction, with enolate ion I as the nucleophile, to yield a fused ring intermediate 2 and Cr. Step 3: Formation of a tetrahedral carbonyl addition intermediate 3 Step...

СО cat. H + NH2CH3 + H2CO2C CO2CH3 CO CHE Cocaine has been prepared by a sequence beginning with a Mannich reaction between dimethyl acetonedicarboxylate, methylamine, and butanedial. The mechanism involves the following steps: 1. Following initial protonation of the carbonyl oxygen, nucleophilic attack by the amine forms carbinolamine 1; 2. Proton transfer and elimination of water forms iminium ion 2; he enol form of the dicarboxylate ester attacks the iminium ion to form adduct 3; 4. Adduct 3 tautomerizes...
