4-Methyl-2-heptanone can be prepared in two ways by the conjugate addition of an organocuprate to an \alpha ,\beta -unsaturated ketone.
Part 1 of 2
Draw the structures of the larger molecular weight lithium organocuprate and the \alpha ,\beta -unsaturated ketone used to synthesize 4 -methyl- 2 -heptanone.
Part 2 of 2
Draw the structures of the smaller molecular weight lithium organocuprate and the \alpha ,\beta -unsaturated ketone used to synthesize 4 -methyl- 2 -heptanone.
