Article abstract of DOI:10.1021/je00050a032

1-Indanone (I) was reacted with aryl aldehydes (II) to give the corresponding 2-arylidene-1-indanones (III).Condensation of the chalcones III with guanidine revealed the formation of the corresponding 5H-2-amino-4-arylidenopyrimidines (V).The structures of all products were substantiated by chemical and spectroscopic methods.
