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

Three-step synthesis of 6-amino-2,3-dihydro-4-pyridinones from homoallylamines involving NBS (or I2, PhSeCl)-mediated cyclization of N-(3-butenyl)ureas to 6-(bromomethyl)-2-iminourethanes, dehydrohalogenation and the novel enolate-carbodiimide rearrangement as a key step has been developed. The...
