Hello everyone, in this question here they have asked that read the three possible starting materials and reagents for the following alkenes.
00:09
So here they have given the alkenes that is here this is a cyclic xanthine and here we have this is our alkene.
00:19
So here they have asked that the methods of synthesis of three methods to synthesis of this alkene.
00:25
So here we are going to start with first method here.
00:29
Here is the method one that is three methods.
00:32
So first one here, here we are going to take the reagent is here it is here we are going to take alcohol that is here it is alcohol that is tertiary alcohol we are going to take here.
00:45
So this is treated with here h2so4 that is strong acid.
00:50
So here what happen here the alcohol is going to be protonated it becomes oh2 here it becomes oh2 plus after that what happens here elimination of water molecule takes place.
01:07
So here what happens it forms tertiary carbocation...
