Urgent retrosynthesis and subsequent synthesis
« on: November 20, 2015, 09:48:21 PM »
Good morning
I need to know how do you develop the retrosynthesis and the synthesis of the two molecules following?

Deputy my proposals,

I hope your important comments

Thank you

First retrosynthetic route in your second problem can be handled with an aldol condensation. Your bond-breaking indication is correct, but your subsequent step is wrong. Are you familiar with aldol condensation/enolates?



Are you starting with benzene or phenol in problem 2? You can take advantage of diazonium in electrophilic aromatic substitution to dictate substituent positioning.

Can bromoacetoacetate self-condense?

Good Morning

I did the synthesis of the two molecules, This proposal is feasible?
Thank you very much
