Amides and sulphonamides act as molecular padlocks in closing an open-chain tetramine around a NiII or a CuII ion, in presence of formaldehyde and triethylamine. Through the above template procedure and using the appropriate RCONH2 or RS02NH2 locking fragments, cyclam-like macrocycles carrying the desired R functional group can be obtained in a one-pot synthesis.

Abstract
Amides and sulphonamides act as molecular padlocks in closing an open-chain tetramine around a NiII or a CuII ion, in presence of formaldehyde and triethylamine. Through the above template procedure and using the appropriate RCONH2 or RS02NH2 locking fragments, cyclam-like macrocycles carrying the desired R functional group can be obtained in a one-pot synthesis.File in questo prodotto:
