The Structure of the Cycloadducts from Alkylimines and 3-Benzoyl-5-phenylfuran-2,3-dione - A Correction With the aid of extended 1H- and 13C-NMR spectroscopy, the 1:1 adducts from 4-benzoyl-5-phenylfuran-2,3-dione (1) and N-alkyl-(phenylmethan)imines 2a-d are found to be furo[3,2-e] [1,3]oxazine derivatives 4, thus correcting previously reported structural proposals.1
