3-oxazines and ,. From the aminoalcohol obtained by Na/EfcOH reduction of 2, the diastereomeric 4-phenyloxazine derivative 8 was obtained. 3 and 4 were transformed through carbamates to cis-5,6-trimethylene- and cis-5i6-tetramethylene-1, 3-oxazin-2-ones 3 and 10, while the analogous 2-thiones and were prepared dithiocarbamates. With phenyl isothiocyanate, furnished the 2-phenylimino-1,3-oxazine , while
