A range of 5H-pyrrolo[3,4-b]pyrazine-based peptidomimetics were designed, and their efficient synthesis starting from 5-imino-5H-pyrrolo[3,4-b]pyrazin-7-amine by subsequent interaction with N-protected amino acid hydrazides and amino acid esters with N,N-carbonyldiimidazole as the coupling agent was elaborated.
Amino Acid Functionalized Organotin Trichlorides and Their Tin Sulfide Clusters

We present a new synthesis of functionalized tin sulfide clusters via organotin trichlorides with boc-protected amino acids (RAAcSnCl3). In this work we used non-polar (alanine, valine, leucine, phenylalanine and methionine), polar/neutral (serine and tyrosine) and basic (histidine) amino acids. We obtained single crystals from a Boc-protected valine derivative of the originally used organotin trichloride R1SnCl3 [R1 = CMe2CH2C(O)Me] and determined its structure by means of X-ray diffraction. A subsequent reaction with sulfide sources led to a variety of respective cluster structures. By using either (Me3Si)2S or Na2S, the reaction product turns out to be the defect-heterocubane cluster [(RAAcSn)3S4Cl] or the “doppeldecker”-type cluster [(RAAcSn)4S6], respectively, according to 119Sn NMR spectroscopy.
