| Abstract: | C-Aryl- and C-carbamoylnitrones reacted with methyl 2-benzylidenecyclopropanecarboxylate in highly regioselective fashion to give the corresponding 1,3-dipolar cycloaddition products, substituted methyl 5-oxa-6-azaspiro[2.4]heptane-1-carboxylates as mixtures of two diastereoisomers. |
