The invention relates to a method for producing peptoidic, peptidic and chimeric peptidic-peptoidic dendrimers by multiple iterative multi-component reactions (MCR), in particular Ugi or Passerini multi-component reactions, to compounds produced in this way and to the use thereof.
purification of the nitrile after the workup was not required. The dehydration reaction of aldoximes and amides for the synthesis of nitriles using [Et2NSF2]BF4 (XtalFluor-E) is described. Overall, the reaction proceeds rapidly (normally <1 h) at room temperature in an environmentally benign solvent (EtOAc) with only a slight excess of the dehydrating agent (1.1 equiv). A broad scope of nitriles can be prepared
A modified Kondrat’eva cycloaddition involving an unprecedented thermally controlled metal-free decarboxylative aromatization affords an expedient access to natural 3-hydroxypyridine/piperidine systems.
This invention is directed to novel antibacterial/antifungal/antiparasitic agents of Formula (I):

A rapid and general access to diversely substituted 5-alkoxyoxazoles 2 (i.e., R1, R2 = alkyl, phenyl) from easily accessible α-triflyloxy/hydroxy esters 1 and nitriles with good yields (41–76%) is reported. The versatility of the cyclization is shown for a range of substrates with high selectivity toward triflates over mesylates and proved to be compatible with sensitive functional groups. As an illustration
