Аннотация:2-Aminoimidazoles (AI) are important part alkaloids obtained from marine sponges. The review is devoted to the synthetic methods leading to 2-AI where the starting material is a heterocycle. Synthesis of AI (monocyclic and fused) from recyclization of aminooxazoles is reviewed; preparation of AI from the other azoles and heterocycles and synthesis of AI pyridines are mentioned. Special attention is given to preparation of 2-AI by six-membered ring cleavage of imidazo[1,2-a]pyrimidines. Wherever possible, the yields and diversity of substituents is given for target structures and special attention is paid to the total synthesis of marine alkaloids.
