Title: How to do this organic conversion
Post by: AussieKenDoll on September 18, 2020, 05:47:07 AM

I am not sure how to get the final -COH group and how to remove the -COOEt group from initial molecule?

You can alkylate using Br(CH)2(CH)2CHO then hydrolysis of Ester followed bydecorboxylation.

What do you know about aldehydes and nucleophiles? And beta-halogenaldehydes and E1cb-mechanism, this is basic conditions?
