Allylboration of imines, nitriles (including hydrocyanic acid), amides, lactams, aromatic azaheterocycles (pyridines, isoquinoline, and pyrrole) was used to synthesize a series of mono- and bis-3-butenylamines with different structures, which were converted to dichloroacetamides, new analogs of a known safener (herbicide antidote) Dichlormid successfully used in the cultivation of corn throughout the

triallylborane and enantiomerically enriched N-Boc-1-phenyl-3-butenylamine was synthesized by the addition of (–)-AllB(Ipc)2 to the corresponding silylimine. Chiral precursors containing a carboxylic ester group were synthesized from (S)-allylglycine and-alanine. The reactions of N-Boc derivatives with NBS smoothly produced the corresponding bromocyclocarbamates either in the form of a single diastereomer or
