Abstract:
1. A process for the synthesis of a compound of formula (I): wherein: m=0 or 1; n and p are the same or different and each is 0 or an integer from 1 to 4; X is a single bond, O, S or NH; R R each R two R wherein: q is 0 or an integer from 1 to 4; Y is a single bond, CH R each R two R wherein: r is 0 or an integer from 1 to 4; Z is a single bond, CH R each R said alkyl groups are straight or branched alkyl groups having from 1 to 20 carbon atoms; said alkenyl groups are straight or branched alkenyl groups having from 2 to 20 carbon atoms; said alkynyl groups are straight or branched alkynyl groups having from 2 to 20 carbon atoms; said aryl groups are aromatic hydrocarbon groups having from 6 to 14 carbon atoms in one or more rings which may optionally be substituted with at least one substituent selected from the group consisting of cyano groups, nitro groups, halogen atoms, hydroxyl groups, carboxy groups, alkoxycarbonyl groups as defined below, alkylcarbonyl groups as defined below, amino groups, alkoxy groups as defined below, alkyl groups as defined above, haloalkyl groups as defined below, alkoxyalkyl groups as defined below, aryl groups, aryloxy groups as defined below and aralkyl groups as defined below; said heteroaryl groups are 5- to 7-membered aromatic heterocyclic groups containing from 1 to 3 heteroatoms selected from the group consisting of sulfur atoms, oxygen atoms and nitrogen atoms, said groups optionally being substituted with at least one substituent selected from the group consisting of cyano groups, nitro groups, halogen atoms, hydroxyl groups, carboxy groups, alkoxycarbonyl groups as defined below, alkylcarbonyl groups as defined below, amino groups, alkoxy groups as defined below, alkyl groups as defined above, haloalkyl groups as defined below, alkoxyalkyl groups as defined below, aryl groups as defined above, aryloxy groups as defined below and aralkyl groups as defined below; said haloalkyl groups are alkyl groups as defined above which are substituted with at least one halogen atom; said alkoxy groups are alkyl groups as defined above that are bonded to an oxygen atom; said haloalkoxy groups are alkoxy groups as defined above that are substituted with at least one halogen atom; said aryloxy groups are aryl groups as defined above that are bonded to an oxygen atom; said alkoxyalkyl groups are alkyl groups as defined above that are substituted with at least one alkoxy group as defined above; said alkylcarbonyl groups are carbonyl groups substituted with a hydrogen atom or an alkyl group as defined above; said alkoxycarbonyl groups are carbonyl groups substituted with an alkoxy group as defined above; and said aralkyl groups are alkyl groups as defined above that are substituted by at least one aryl group as defined above; said process comprising reacting a compound of formula (IV): wherein R
