    Abstract: Benzofuram derivs.of formula (I) are new: R = R' = H or R + R' = a bond; R1 and R2 = H, 1-4C alkyl or phenyl(1-4C)alkyl; Ar = phenyl with 0.3 substits. selected from benzyloxy, F, Cl, Br, OH, 1-6C alkoxy, NH2, mono- or or di(1-4C alkyl)amino, 1-4C acylamino, NO2, CH2OH and 1-4C alkyl or two adjacent substits. are linked to form CH=CH-NH; R4 and R5 = H, 1-4C alkyl or phenyl(1-4C)alkyl, where the phenyl gp. is opt. mono- or disubstd. by F, Cl, Br, 1-4C alkoxy, NH2, mono-or di(1-4C alkyl)amino or NO2, or R4 + R5 = a 3- to 6-membered chain opt. contg. an O or N atom and opt. fused with a benzene ring opt. substd. by F, Ce, Br, 1-4C alkoxy, NH2, mono-or di(1-4C alkyl)amino or NO2; X = COCH=CH, COCH2CH2 or CH(OH)CH2CH2; n = 2 or 3; provided that when R1 = R2 = Me, then R4 = H or alkyl and R5 = opt. substd. phenylakyl or R4+R5 = a 3- to -6 membered chain (opt. contg. O or N) fused with an opt. substd. benzene ring.
