Yields of isolated, purified products; endo/exo ratios determined by ¹H NMR analysis; ee determined by chiral-phase HPLC and only shown for endo diastereomer (see SI for details). Reaction conditions: (a) 1a, 2a, 2,6-lutidine, CH₂Cl₂; (b) 1b, 2b, (−)-BTM, CH₂Cl₂; (c) 1b, 2b, DTBP, (−)-BTM. DTBP = 2,6-di-tert-butylpyridine.
