perhydrogenated derivatives were prepared from the corresponding 2-hydroxycarboxamides by treatment with a formaldehyde/formic acid mixture. Thermal decomposition of the 3-hydroxymethyl derivatives led to the previously unknown parent compounds. With one exception (14), both in the N-unsubstituted (16–18) and in the N-substituted (7–15) cyclopentane- and cyclohexane-fused derivatives the oxazinone ring
