Q3] Propandial was treated with 1 mole of methylproenoate in the presence of NaOCH3 forming compound "A. Again "A was treated with another mole of NaOCH3 under heat to form compound "B". The compound "B" was treated with one mole of NaH affording "C". Magnesium in dry ether was added to "C" and then heated providing "D". Conc. H2SO4 was refluxed with "D" then ozonolyzed to give "E". What are structures A...to.....E?? A B D E Q3] Propandial was treated with 1 mole of methylproenoate in the presence of NaOCH3 forming compound "A.
