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

and acid anhydrides to form bis-allyl amines and esters, respectively, can be achieved through the use of potassium allyltrifluoroborate in the presence of boron trifluoride etherate at room temperature. The method described is relatively mild, exhibits chemoselectivity to other electrophiles present, avoids the use of metals, and features the use of an operationally stable and robust potassium organotrifluoroborate

A method of producing a 6-substituted (S)-nicotine derivative with the general formula (III), wherein R is an optionally substituted alkyl, alkenyl, alkynyl, amido or amino group, optionally coupled to a carrier protein, is disclosed. An intermediate compound useful in the method is also comprised by the invention. The formula of the compound is (A) in which A represents the cationic radical of an organic nitrogen base, Y represents an anion formed by an electrophilic compound.
Compounds of Formula (1), wherein R1 is hydrogen; C1-C18alkyl; trifluoromethyl; C3-C8cycloalkyl; phenyl-C1-C5alkyl; phenyl-C1-C5alkoxy; mono- or di-N-C1-C5alkylamino-C1-C5alkyl; amino-di-N-C1-C5alkylamino-C1-C5alkyl; C1-C5alkoxy-C1-C5alkyl; R2 is C2-C20alkyl; hydroxy-C1-C20alkyl; phenyl; phenyl-C1-C5alkyl; phenyl-C1-C5alkoxy; mono- or di-N-C1-C5alkylamino-C1-C5alkyl; amino-di-N-C1-C5alkylamino-C1-C5alkyl; or heteroaryl-C1-C5alkyl; or R1 and R2 together with the nitrogen atom bonding them form a 5- to 7-membered monocyclic heterocyclic ring; are described. They are suitable for the antimicrobial treatment of surfaces, especially as antimicrobial active ingredients against gram-positive and gram-negative bacteria.
