A process for the multigram asymmetricsynthesis of the chiral tetraazamacrocycle 2-(R)-2-(4,7,10-tris tert-butylcarboxymethyl-1,4,7,10-tetraazacyclododec-1-yl)-pentanedioic acid, 1-tert-butyl ester ((R)-tert-Bu4-DOTAGA, 4) has been devised and demonstrated. The nine-step synthesis features an improved synthesis of 2-(S)-5-oxotetrahydrofuran-2-carboxylic acid, tert-butyl ester 8, the precursor to the
Two α-aminoxy diamides with fluorinated side chains were synthesized. Their secondary structures characterization was carried out by 1H NMR, and IR spectrometries as well as X-ray crystallography studies. α N–O turn secondary structures are adopted insusceptibly by side-chain-fluorinated α-aminoxy residues. Thus the fluorinated α-aminoxy diamide can be a potential residue as a biological tracer to
合成了两个带有氟侧链的α-氨基二酰胺。它们的二级结构表征是通过1 H NMR,IR光谱以及X射线晶体学研究进行的。侧链氟化的α-氨基氧基残基不易采用αN–O转向二级结构。因此,氟化的α-氨基二酰胺可以是潜在的残基,作为掺入氨氧基肽中的生物示踪剂。
