NEW 3,11-DIMETHYL-2-NONADECANE SILYL ETHER, ITS PRODUCTION, PRODUCTION OF ITS PRECURSOR AND PRODUCTION OF SEX PHEROMONE OF GERMAN COCKROACH (BLATTELLA GERMANICA) USING THE SAME

摘要

NEW MATERIAL:3,11-Dimethyl-2-nonadecane silyl ether of formula I (R1 and R2 are H, alkyl or phenyl; X is tert-butyl). EXAMPLE:(2R,3S,11S)-2-tert-butyldimethylsilyloxy-3,11-dimethylnonacosa none. USE:An attracting and controlling agent for German cockroach (Blattella germanica). PREPARATION:The compound of formula I can be produced e.g. by condensing a silyl ether of formula II [e.g. anti-(5S,6R)-6-tert-butyldimethylsilyloxy-5- methyl-2-heptanone] and 4-methyl-1-docosyl iodide of formula III and reducing the obtained nonadecane skeleton.
