In one case, the addition took place with partial cis-->trans inversion of the starting compound. Adduct (7), containing two condensed 1,3-oxazine rings, was also isolated. The stereostructures of the new compounds were proved by H-1 and C-13-nmr spectroscopy, with NOE measurement data. The reaction mechanism is discussed. %Z Saját lista sorszáma: 317 (S.P.)
