Fungicidal title compds. (I; R1,R2,R3 = C1-8 alcohol; aryl, C3-6 cycloalkyl, C3-6 alkoxyalkyl, benzyl, phenyl, substituted phenyl, or R1 = hydroxyphenyl, R2 = H, furfural, R3 = H) were prepd. by reaction of carbamoylchloride(II) and thiourea(III) in the presence of base. Thus, 3.4 g(0.02 mol) II(R1 = iso-C3H7) in 50 ml C6H6 and 3.3 g(0.02 mol) III(R2 = -C6H5; R3 = Me) were stirred for 2 hr under refluxing, filtered, washed, extracted with C6H6, and recrystallized with isopropylalcohol to give 2.1 g(40%) I (R1 = iso-C3H7; R2 = -C6H5; R3 = Me).
