The preparation of the paraxanthine, theobromine and theophylline isomers 1,5‐; 2,5‐ and 1,7‐; 2,7‐ and 5,7‐dimethyl‐4,6‐dioxo‐4,5,6,7‐tetrahydro‐pyrazolo[3,4‐d]‐pyrimidines is described and their structure established. A structurally specific synthesis of the caffeine and isocaffeine isomers 1,5,7‐ and 2,5,7‐trimethyl‐4,6‐ dioxo‐4,5,6,7‐tetrahydro‐pyrazolo [3,4‐d]pyrimidines has been realized.
