1. The reactions of 2-amino-4-picoline and 2-amino-3-picoline with diketene, ethyl acetoacetate, and ethyl β-aminocrotonale
2. 9-Hydroxy-2-methyl-4H-pyrido[1,2-α] pyrimidin-4-one and its derivatives
3. In contrast, while 8-hydroxyquinoline forms a deep-red, insoluble sodium alkoxide, at room temperature, it can literally be “titrated” with a variety of alkylating agents, i.e., the deep-red solid and solution, in each instance, change to yellow when precisely one molar equivalent of the alkylating agent has been added (Unpublished studies by the author).
4. The preparation, structure and reactions of some “malonyl-α-aminopyridines”
