Two efficient large scale syntheses of (Z)-(1-bromobut-1-ene-1,2-diyl)dibenzene are described. The first is a three-step synthetic sequence from trimethyl(phenylethynyl)silane in 63% overall yield. The key transformations involved the stereospecific

High yields of several thiolesters of 2-[3-(4-cyanophenyl)-4,5-dihydro-5-isoxazolyl]acetic acid are easily prepared from the corresponding oxoester by the reaction with trimethyl silylated mercaptan and aluminum chloride. The selection of mercaptans
