[28] For some products (20, 22, 24, and 26) we obtained their O-
benzoylated adducts for structure confirmation (see SI) due to the
complicating equilibrium between cyclic and acyclic forms in CDCl3. For
example, see: F. Pesciaioli, F. De Vincentiis, P. Galzerano, G.

reported by Ali for his substrates 14b, 15b did not succeed in our hands.
Instead, we observed a 1:1 mixture of regioisomers.

[34] This value was established at the final stage when epi-4 was isolated
as the major product.

[22] The structural assignment of 33 was confirmed after N–O reductive
cleavage (see SI for details).
[23] 5-membered nitrones under these conditions suffered from poor yields
(<10%) due to the relatively slower reaction rate consistent with the
same observation for [3+2]-cycloadditions (cf. ref. 9b). When the same
conditions were applied to a 7-membered nitrone, only a small amount
of desired product was observed along with decomposition, perhaps
due to prolonged acidic treatment: Y. Imada, C. Okita, H. Maeda, M.

[25] At this stage, the optical rotation, and thus absolute configuration of 31,
was confirmed after reductive cleavage of the N–O bond (see SI for
details).
