SUBSTITUTED 1,3-DIOXOLANE AND 1,4-DIOXANE DERIVATIVE

摘要

Alpha-phenoxy or pyridyloxy-omega-dioxanyl-alkane derivs. of formula (I) are new. In (I), R1-R6 = H or 1-4C alkyl or, if n = 1, R2 and R4 are together (CH2)3 or (CH2)4; R7 = H, halo, 1-2C alkyl (opt. substd. by 1-5 halo) or 1-2C alkoxy (opt. substd. by 1-5 halo); R8 = halo, 1-3C alkyl (opt. substd. by 1-7 halo), 1-3C alkoxy (opt. substd. by 1-7 halo) or CN; U = CH or N; X = O, S or NR9; Y = O, S, SO, SO2, CH2, CO or NR9; R9 = H, 1-4C alkyl or 2-4C alkylcarbonyl; n = 0 or 1; m = 0-2; p = 1-3; z = a gp. of formula (i); R10 = H, Me or Et; R13 and R14 = H, halo or 1-3C alkyl, or together are (CH2)4. Specifically claimed are 2-(4-(2-,3- or 4-fluorophenoxy)) phenoxymethyl-1,4-dioxan; 2-(4-(3- or 4-fluorophenoxy)) phenoxymethyl-6-methyl -1,4-dioxan and 2-(4-(4-fluorobenzyl)) phenoxymethyl-1,4-dioxan.
