A process for the preparation of tetraazamacrocycles |
| abstract |
A process for the preparation of tetraazamacrocycles of general formula (I), wherein n, p and q can independently be 0 or 1, comprising the following steps: a) condensation of polyamines with a glyoxal derivative; b) condensation of the resulting compound with an alkylating agent; c) oxidation of the resulting compound with an oxidizing agent, to give a mixture of oxidated products which is submitted to d) hydrolysis in acid aqueous solution, to give the compound of formula (I). |
