  • Patent number: 4723037
    Abstract: The invention provides a novel process for making novel (4-phenyl-1,3,-dioxan-cis-5-yl)alkenoic acids of the formula I in which Ra and Rb are independently hydrogen, alkenyl, alkyl, halogenoalkyl, pentafluorophenyl, aryl or aryl-(1-4C)alkyl; or Ra and Rb together are polymethylene; Rc is hydroxy or (1-6C)alkanesulphonamido, A is vinylene, n is 1, Y is polymethylene, and benzene ring B bears various optional substituents. The process involves the reaction of an aldehyde of formula II with an ylid to give an erythro-diol of formula III which is then cyclized to the required dioxane derivative of formula I. The invention also provides a novel process for making the aldehydes of formula II from the corresponding lactols of formula IIa, which are themselves obtained with the correct trans-stereochemistry by two selective reductions of a trans-phenylparaconic acid of formula V. The compounds of formula I are useful as therapeutic agents.
