Synthetic Route of 21436-03-3. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine
An efficient and simple method for the synthesis of chiral benzo[5,6][1,3]oxazino[4,3-c]quinoxalinedione and octahydroquinoxalino-[1,2-c:4,3-c?]diquinazolinedione derivatives using 2-hydroxybenzaldehydes (or 2-nitrobenzaldehydes) and chiral cyclohexane-1,2-diamine as the starting materials promoted by low-valent titanium reagent has been described. The structures of all synthesized products were identified by their IR, 1H NMR, 13C NMR and HRMS analysis, and the structure of compound 8b was confirmed by X-ray diffraction analysis.
