Create the following structure starting with a keytone
« on: March 21, 2010, 11:10:18 PM »
Q:Create the following structure starting with a keytone.

Solution:
Would the following synthesis work by conversion of the keytone to an enolate?  The lithium diisopropylamide obviously removes a hydrogen from the less substituted side. ;D

You're using chloroethane when you only want to introduce a methyl group. Should be chloromethane.
