A new method was developed for the synthesis of 2-aryl- and 3-aryl-2-buten-4-olides by the arylation of 2-buten-4-olide with diazonium halides in the presence of cupric chloride as catalyst.The intermediate products of the reaction are the corresponding arylchlorobutanolides. 4-R-Methylene-3-aryl-2-buten-4-olides and 4-hydroxy-3-aryl-2-butenamides were obtained in the reaction of 3-aryl-2-buten-4-olides with aldehydes and primary aliphatic amines respectively.Some of the synthesized compounds have antimicrobial and growth-stimulant activity.
