    Abstract: Preparation of monoacetylated hydroquinone compound comprises reacting a dicetylphenol compound with peroxo compounds optionally using an acid in one reaction step. Preparation of monoacetylated hydroquinone compound of formula (I) comprises reacting a dicetylphenol compound of formula (II) with peroxo compounds optionally using an acid. R1-R3 = H or Me. Independent claims are included for: (1) preparation of (II) by reacting phenol compounds of formula (III) with an acetylation agent using an acid catalyst; (2) preparation of monoacetylated hydroquinone compounds (I) by reacting (III) with an acetylation agent using an acid catalyst to give (II) and further reacting with peroxo compounds, optionally in the presence of an acid; and (3) compounds of formula (Ia)-(Ie).

    Abstract: Preparation of substituted chroman derivatives in multi-stage process from acrolein-aldehyde starting material via new intermediates. Preparation of substituted chroman derivatives of formula (VII) comprises: (a) reacting an acrolein-aldehyde of formula (I) with an acrylonitrile-, acrolein-, acrolein-acetal-, allyl-alcohol- or allyl ether of formula (II) to give the corresponding 3,4-dihydro-2H-pyran of formula (III); (b) treating (III) with an acid to give the corresponding 5-oxo derivative of formula (IV); (c) reacting this with a substituted vinyl-ketone of formula (V) to give a chromen-6-one of formula (VI); and (d) dehydrating to give (VII). X = CN, COOR3, CHO, CH2OR7 or CH(OR8)2; R1 = 1-4C alkyl, 6-18C aryl, 7-18C aralkyl, optionally halogenated 1-4C acyl or an acid labile hydroxy protecting group; R2 = 1-23C alkyl, 2-23C alkenyl, 6-18C aryl or 7-18C aralkyl; R3 = H, 1-4C alkyl, 1-4C haloalkyl, 1-4C hydroxyalkyl or 1-4C aminoalkyl; R4-R6 = H or 1-4C alkyl; R7 = H or 1-4C alkyl; R8 = 1-4C alkyl; or R8+R8 = 2-6C alkenyl optionally branched and optionally substituted by 1-2 carboxyl, cyclohexyl or phenyl. Independent claims are included for: (1) pyran derivatives (III) as new; (2) preparation of (III) using step (a) as above; (3) tetrahydropyran derivatives (IV); (4) preparation of (IV) using steps (a) and (b) as above; (5) chromen-6-one derivatives (VI); (6) preparation of (VI) using step (c) as above.
