  Solid-phase synthesis of 6,7-cycloalkane-fused 1,4-diazepane-2,5-diones via a cyclization/release strategy

  摘要：

  A solid-phase synthesis procedure for the parallel preparation of 6,7-cycloalkane-fused 1,4-diazepane-2,5-diones is described. The methodology applies alpha- and alicyclic beta-amino acid building blocks to construct the seven-membered heterocyclic core, while alcohols are used for further skeletal decoration. The use of a cyclization/release strategy permits the isolation of the target cyclic alpha,beta-dipeptides in good crude purities and generally moderate to good yields. A 26-membered model library is reported and NMR spectroscopical data are used to describe the overall conformational behaviour of the obtained homodiketopiperazines. (C) 2015 Elsevier Ltd.

  Large-Scale Syntheses of FMOC-Protected Non-Proteogenic Amino Acids:  Useful Building Blocks for Combinatorial Libraries

  摘要：

  Convenient and reliable large-scale procedures for the protection of various amino acids with N-(9-fluorenyimethoxycarbonyl)oxysuccinimide (FMOC-OSu) are described. Commercially available 4-aminomethylbenzoic acid and trans-4-(aminomethyl)cyclohexanecarboxylic acid were converted into their corresponding FMOC-derivatives in excellent yields without the need for an extractive workup. In addition, FMOC-cis-beta -amino acids were also prepared, employing a [2 + 2]-cycloaddition strategy between a cyclic olefin and N-chlorosulfonyl isocyanate (CSI). The resulting N-chlorosulfonyl fl-lactams were reduced to the parent beta -lactams with sodium sulfite and then converted to the cis-fi-amino acid hydrochlorides by exposure to aqueous hydrochloric acid. The resulting cis-fi-amino acids were converted to their FMOC-derivatives under conditions similar to those developed for the commercially available amino acids. Differences in the conditions employed between these beta -amino acids and the commercial derivatives were observed, primarily in the nature of the base required for the reaction. A possible rationale for the differences in behavior is described. These FMOC-amino acid derivatives are valuable intermediates for the solid-phase synthesis of combinatorial libraries.
