  A microwave-assisted, one-pot, two-step protocol was developed for the construction of polysubstituted 2-aminoimidazoles. This process involves the sequential formation of imidazo[1,2-a]pyrimidinium salts from readily available 2-aminopyrimidines and alpha-bromocarbonyl compounds, followed by opening of the pyrimidine ring with hydrazine.

  A short and efficient route to 1,4-substituted 2-aminoimidazole alkaloids starting from the easily accessible 2-alkylaminopyrimidines and α-bromo aldehydes is reported. The formation of the intermediate imidazo[1,2-a]pyrimidinium salts and subsequent cleavage were facilitated by microwave irradiation. Marine sponge alkaloids preclathridines A, C and isonaamines A, C, D were obtained in high yields using the optimized one-pot two-step procedure.

  A new divergent and efficient synthesis of substituted 2-aminoimidazoles 5 and 6 has been developed starting from the readily available 2-aminopyrimidines 1 and alpha-broinocarbonyl compounds 2, Using conventional heating or microwave irradiation. Thus, the cleavage of 1,2,3-substituted imidazo[1,2-a]pyrimidin-1 -iumsalts 4 with hydrazine or secondary amines led to 1,4,5-trisubstituted 2-aminoimidazoles 5, when the hydrazinolysis of 2-hydroxy-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-4-ium salts 3, followed by a novel Dimroth-type rearrangement, resulted in formation of 2-amino-1H-imidazoles 6. The relevant pathway of transformations was identified by characterization of the intermediates.

  The isolation and structure determination of the naturally occurring LTB4 receptor antagonist Leucettamine A (1) was recently reported.1 Herein we describe the synthesis of this natural product, the preparation of several analogues, and their effectiveness as antagonists of [H-3]LTB4 binding to intact human U-937 cells. Total synthesis of Leucettamine A 1) is achieved by a convergent route which takes advantage of the elements of symmetry within the molecule. Syntheses of analogues of 1, which lacked the same degree of symmetry, are achieved by a different approach starting from alpha-amino acids. The natural product 1 inhibits [H-3]LTB4 binding to its receptors on intact human U-937 cells with a K(i) = 3.5 +/- 0. 8 muM and is devoid of measurable agonist activity at the concentrations tested. 2-Amino imidazole analogues of 1 lacking the dioxolane groups were prepared. Generally these are significantly less potent than 1. However, one (26), designed on the basis of a putative structural overlay with LTB4, demonstrated potency comparable to that of the natural product (K(i) = 2.4 +/- 0.2 muM).
