Title: GOC question
Post by: Gameofketones on August 13, 2020, 04:07:42 AM
Am I correct so far?

Its really not very good to alkylate alkyllithium compounds with alkyl iodides, better make cuprate. Its possible it works but very slow. Also its likely you get halogen-metal exchange rather than substitution.

@OP, What sort of reaction do you intend for A to B?

A to B....  has an alkene and a diene..  Did they teach you Diels-Alder?

Yes isn't what I did diels Alder from A to B?

@OP, What is the product of a standard Diels-Alder reaction?

The alkene is not a dienophile, but still give DA?

Rolnor - you CAN force 1,3-butadiene and ethene to do a Diels-Alder reaction at high pressure.  This is a paper synthesis - being intra molecular is a little like higher pressure!  I don't see what else an alkene and diene will do with just heat.

These questions don't concern with the actual practicability of the reaction. These are just practice questions.

Then do an intramolecular Diels-Alder reaction correctly.

Yeah, my bad..I was going for Diels Alder but messed it up

OK, I understand.
