    Abstract: Novel substituted 2-pyrones

    IN WHICH ONE OF THE RADICALS R1 to R4 is substituted by an acryloyl or methacryloyl group are obtained from the corresponding 2-pyrone derivatives and acrylic or methacrylic acid or a derivative thereof. The compounds can be polymerized forming light-sensitive polymers which are cross-linked by the action of light and may be used in light-sensitive copying layers.

    Abstract: Compounds of the formula (I) wherein one of the radicals R1, R2 or R3 denotes a straight-chain alkyl group having 4 to 8 C atoms and two vicinal hydroxyl groups in the omega , omega -1 or omega -1, omega -2 positions and the two other radicals represent straight-chain or branched alkyl groups having up to 12 C atoms in the position of R1 and R3 and up to 4 C atoms in the position of R2, the total of C atoms in these two alkyl substituents being a maximum of 14, are prepared by oxidation of the corresponding alkenylxanthines and by alkylation with compounds which introduce the dihydroxyalkyl radical or a precursor thereof. The dihydroxyalkyldialkylxanthines are suitable for the treatment of obstructive respiratory tract diseases.
