Controlled protonation of methane(tri-α-diazoacetone) (1) leads to open-chain tricarbonyl compounds 2, which can be cyclized by acids to 2,4,9-trioxaadamantanes 3. On the other hand, the base-induced cyclization of methane(tri-chloroacetone) (2, X Cl) leads to a triasterane derivative: 1-hydroxymethyltetracyclo-[3.3.1.04,6]nona-3, 7-dione (4).
