So I am trying to find some peer reviewed journals to reference for a formal report on the chitosan catalyzed synthesis of imines. I used vanillin and aniline to produce 2-methoxy-4-phenyliminomethyl-phenol. I'm looking for three to four sources to discuss chitosan (I already have two so I don't need for this so much), the function of imines in organic chemistry, and medicinal properties of imines. I have been searching for hours now and can't find anything other than for chitosan.
Would anyone be able to direct me to a few references please?
Thanks in advance
