| titleOfInvention | Process for the preparation of optically active alpha-arylalkanoic acids and novel intermediates thereof |
| abstract | ABSTRACT OF THE DISCLOSURE The invention provides optically active esters of alpha arylalkanoic acids of formula (C) in which Ar represents a monocyclic, polycyclic, or orthocon-densed polycyclic aromatic or heteroaromatic group having up to 12 carbon atoms in the aromatic system which group may be substituted by one or more halogen atoms, C1-C4 alkyls, C3-C6 cycloalkyls, benzyl, hydroxyl, alkali metal oxygen, C1-C4 alkoxy, C1-C4 alkylthio, C1-C4 haloalkyl, C1-C4 haloalkoxy, phenoxy, thienylcarbonyl and benzoyl; R represents a linear or branched C1-C4 alkyl radical; R1 and R2, which can be equal or different, represent a hydorxy, O-M+, OR3 or NR4R5, wherein R3 is C1-C24 alkyl, C3-C6 cycloalkyl, phenyl or benzyl; M+ is the cation of an alkaline metal; R4 and R5, which can be the same or different, represent a hydrogen atom, a C1-C4 alkyl, C5-C6 cycloalkyl, or a -(CH2)n-CH2OH where n is 1, 2 or 3 or R4 and R5 together form a -(CH2)m- group where m is 4 or 5 or a -CH2-CH2-R7-CH2-CH2- group where R7 is an oxygen atom, an NH or a N-(C1-C4) alkyl group and R6 is OH, Cl, Br, I or acyl radical which are intermediates in the production of optically active alpha-aryl alkanoic acids. |
