Fig. 3 — Naito stereocontrol model proposed for additions to camphorsultam-functionalized glyoxylic oxime ethers.

(a) Lewis acid chelation induces rigidity and electron-deficiency into the N-acylhydrazone radical acceptor (LA = Lewis acid). (b) Benzyl substituent of 4-benzyl-2-oxazolidinone provides facial diferentiation of the C=N bond.
