## Abstract Divergent acid‐catalysed ring‐openings of 4,5‐dimethoxytetrahydropurine‐2,6,8‐triones 2 at position 4, yielding 1‐(5‐methoxyhydantoin‐5‐carbonyl)ureas 4 (R^7^ = Me) or 5‐methoxy‐5‐ureido‐2,4,6‐pyrimidinetriones 5 (R^7^ = H), can be rationalized by assuming a preference for one of two co
Conformational ;f;ects in 1,3-dioxans and 1,3-dithianes have been recently largely elucidated. -That is why we started a systematic study of alkyl-substituted 1,3-oxathianes to compare their conformational features with those of their above-mentioned symmetric analogs. GELAN and ANTEURIS investigat
