    What other methods of chain homologation do you know?

    i was thinking of acetyl chloride and then N-methylethanamide... that will give me 3 carbons... but then how to get rid of nitrogen and bring OH?

    Can you draw some structures? Seems like N-methylacetamide has the wrong carbon backbone too.

    yeah... that's where i'm stuck... i really have no idea on how to bring the carbon inside!!

    how about this:
    acetyl chloride then diazoketone then wolff rearrangement and then water! right?
