专利号:EP-0178580-B1 优先权日:1984-10-15 标题:Intermediates for the synthesis of carboxylic acids 摘要:The compounds of formula: in which Ar represents an aryl, possibly substituted; R represents a C1-C4 alkyl; X represents a hydrogen, chlorine, bromine or iodine atom, a hydroxyl, or an acyloxy, alkylsulphonyloxy or arylsulphonyloxy group; n represents 0 or 1, where if n=0 one of R1 and R2 represents a -CH2OH group and the other represents a hydrogen atom, and if n=1 both R1 and R2 represent hydrogen atoms; are useful intermediates in the preparation of alpha-arylalkanoic acids by rearrangement reactions. The compounds of formula I are prepared by reacting glycerin or one of its anlogues with the appropriate alkyl-aryl-ketone.
