    • The cyclopropane C-C bonds toward its apex extending from C-4 and C-5 are significantly longer in N-Boc 2 compared to N-Boc 3, indicating a relatively less rigid ring (ref 12).

    • The iminium ion A may also benefit from a through space interaction with the electron-rich cyclopropane ring.
