  This invention relates to a process for the preparation of pyrimidinone compounds of the formula ##STR1## wherein Ar is an optionally substituted aryl or heteroaromatic moiety, R.sup.3 is an optionally substituted alkyl, alkenyl or alkynyl, R.sup.5 is a hydrogen atom, halo, cyano or an optionally substituted alkyl, alkenyl, alkynyl, alkoxy or alkylthio, and R.sup.6 is a hydrogen atom, cyano, or an optionally substituted alkyl, cycloalkyl, alkenyl, alkynyl, aryl, aralkyl or heteroaryl. The process comprises reaction of an amidine and a malonic acid derivative to give a hydroxypyrimidinone followed by conversion of the resulting hydroxypyrimidinone to a sulfonyloxypyrimidinone followed by reaction of the resulting sulfonyloxypyrimidinone with an organometallic reagent to give the desired pyrimidinone. The hydroxypyrimidinones, wherein R.sup.6 is hydroxy and sulfonyloxypyrimidinones wherein R.sup.6 is a substituted sulfonyloxy moiety, are themselves new and useful intermediates in the preparation of the desired pyrimidinones.

  这项发明涉及一种制备嘧啶酮化合物的过程，其化学式为##STR1##其中Ar是一个可选择取代的芳基或杂环芳基，R.sup.3是一个可选择取代的烷基、烯基或炔基，R.sup.5是一个氢原子、卤素、氰基或一个可选择取代的烷基、烯基、炔基、烷氧基或硫代烷基，R.sup.6是一个氢原子、氰基，或一个可选择取代的烷基、环烷基、烯基、炔基、芳基、芳基烷基或杂环芳基。该过程包括使脲酰胺和丙二酸衍生物反应，得到羟基嘧啶酮，然后将所得的羟基嘧啶酮转化为磺酰氧基嘧啶酮，随后将所得的磺酰氧基嘧啶酮与有机金属试剂反应，得到所需的嘧啶酮。其中R.sup.6为羟基的羟基嘧啶酮和R.sup.6为取代磺酰氧基的磺酰氧基嘧啶酮本身是制备所需嘧啶酮的新颖有用的中间体。
