摘要

Abstract The synthesis and structure analysis of the unknown 1H-imidazo [1, 2-a] imidazole (1) is described. The preparation involves alkylation of 2-aminoimidazole with bromoacetaldehyde diethyl acetal and subsequent hydrolysis and cyclization with hydrochloric acid. The structure was characterized by mass spectrometry and by 1 H-, 15 N- and 13 C-nmr of 1 and by 1 H-nmr of its 1-benzyl derivative 8. An independent synthesis ...
