As per our interest to develop better protocols for the synthesis of biologically active heterocyclic molecules, we would like to report the synthesis of a series of new 3,4-dihydro-3-substituted-2H-naphtho[2,1-e][1,3] oxazine derivatives using 2 naphthol, formalin and various anilines as substrates in presence of Potassium Dihydrogen Phosphate catalyst.
Thirty-three phenolic compounds, chiefly phenol, alkyl phenol, thymol, naphthol and alkyl naphthol, were identified in the concentrated product 2 by GC-MS, with the relative content of 87.57%.
Using quantitative measures, we investigated the contributions of dermal and inhalation exposure to JP-8 to urinary naphthols levels.
Due to a variety of applications of the described amidoalkyl naphthol compounds, and in continuation of our previous works on the synthesis of amido/thioamidoalkyl naphthols [58, 59], in this contribution, the catalytic activity of SA as an efficient and cost-effective organocatalyst has been explored for the synthesis of 1-amido/thioamidoalkyl-2-naphthols (4a-v) in MCR under SFRCs protocol (Scheme 1).
