摘要

Title compds. are of formula: R1Y.CR2R3.(CH2)w.CR4R5.(CH2)zXR6 (I), (where R1 = 1-11C alkyl, unsatd. 3-11C hydrocarbyl, or 5-7C cycloalkyl opt. substd. by 1-6C alkyl; R2-R5 = 1-6C alkyl; w and z = 0-8 (w+z= 1-8); Y = O or S; X = O, S, OCH2, SCH2, OCHR7 or SCHR7; R7 = 1-4C alkyl; and R6 = where U = 1-6C alkyl, alkenyl, Ph, l. alkoxy, CHO, l. alkylcarbonyl, l. alkoxycarbonyl, alkyl or dialkylcarbamoyl, l. alkoxymethylene, l. alkylthio, CN, Cl or Br; R8 and R9 = H or 1-6C alkyl; W = NO2; m = 0-2; n = 0-3; m+n = 1-5; p = 1 or 2 and q = 0-2; provided that R2 = 1-6C alkyl when x = OCHR7 or SCHR7 or when x = OCH2 or SCH2 and R6 = (III) and/or z = 1-4 and z+w = 1-4), (I) are synthesised in various ways by condensing appropriate fragments, e.g. from R1Y.CR2R3(CH2)wCR4R5(CH2)zQ', and M'XR6, (where Q' = Cl, Br or tosyl and M' = H, Na or K, or from Q'CHR3(CH2)wCR4R5(CH2zXR6 and M2YR1, where M2 = H or K).
