Reaction of conjugate addition
This reaction is a "conjugate addition" of cyanide ion on a cyclopropane. Notice that reaction at the least branched carbon of the cyclopropane happens and that the immediate product of ring opening is a very stable anion. Heating in acid protonates this anion, hydrolyzes the ester and nitrile groups, and decarboxylates the resulting β -keto acid.
