摘要

Use of oxazoline derivs. of formula (I), other than 2-(2,6-difluorophenyl)-4-(4-(4-trifluoromethoxyphenyl)-phenyl)-2-oxazo line, for controlling endoparasites in humans and other animals is new: B = opt. substd. alkyl, alkenyl, cycloalkyl, cycloalkenyl or aryl; A = A' or ZA'; A' = opt. substd. aryl, aryloxy, heteroaryl or heteroaryloxy; Z = a divalent gp.; R = H; or A+R forms an opt. substd. spirocyclic 3- to 6-membered ring which opt. contains one or more heteroatoms (O, S, N) and is opt. fused to another ring. (I) are described, e.g., in WO 9321165, 9324470, 9322297 and 9325077, JA 4-89484, 6-145155, 6-145169, 6-48907, 6-100546, 6-100560 and 6-73030, and EP 345775, 432601 and 553623.
