A Practical Synthesis of Hydroxyl-N-tosylcyclams via Cyclization of 1,3-Dichloro-2-propanol with Disodium Di(Poly)-N-Tosylamides
摘要:
Cyclization of 1,3-dichloro-2-propanol with di(poly)-N-tosylamides in the presence of sodium ethoxide in ethanol under reflux conditions gave hydroxyl-N-tosylcyclams in moderate yields. This procedure presents a practical and facile method for synthesis of [1+1] all-nitrogen cyclams.
