| Abstract: | A series of 3-monosubstituted, 3,3′-disubstituted, and 3,5-disubstitted perhydro-7a-methyloxazolo[3,4-c]oxazoles has been synthesised. Some indication of the predominant conformations of these systems and of the related perhydro-imidazo[1,5-c]thiazoles is obtainable from the magnitude of the geminal coupling constants of the methylene group protons situated between the heteroatoms. |
