Question

Question: Draw the product of the following reaction, one step in the synthesis of the antiplatelet agent clopidogrel used to reduce the risk of stokes.

Short answer

Answer

Step-by-step solution

Step-by-Step SolutionStep 1: Clopidogrel

Clopidogrel can be combined with aspirin to ward off problems related to the heart. It comes in the form of a tablet and can be consumed via the mouth.

Substitution reactions

Substitution reactions can be of numerous kinds, and one among them is an ${\mathbf{S}}_{\mathbf{N}}\mathbf{2}$ reaction. The nucleophile strikes from the backside in an ${\mathbf{S}}_{\mathbf{N}}\mathbf{2}$ reaction, and an inversion of configuration is observed.

 Step 3: Synthesis of clopidogrel

Potassium carbonate functions as the base in this particular reaction. It forms a nucleophile by abstracting the most acidic proton of the reactant.

When the nucleophile reacts with the tosyl group, it strikes on the carbon atom of the C-OTs bond from the backside removing the –OTs group, which is a good nucleophile. This reaction goes via the mechanism. The product of the ${\mathrm{S}}_{\mathrm{N}}2$reaction can be given as:
