  Double Annulative Cascade of Tryptophan-Containing Peptides Triggered by Selectfluor

  摘要：

  A common dearomative strategy toward the kapakahines B/F and chaetominine natural products is reported. The proposed biomimetic strategy generates the tetracyclic alpha-carboline core in a single step, featuring a selectfluor-mediated dearomatization of preactivated N-Phth-Trp-Xaa-OR dipeptides at the C-terminus. The pivotal cascade includes a double annulation and the formation of three carbon-heteroatom bonds while gaining, for the first time, some insight on the diastereoselectivity outcome during the formation of the alpha-carboline fragment.

  Rational inhibition: Conjugates of procainamide were produced by rapid synthetic pathways. Several compounds resulted in extremely potent inhibitors of the murine catalytic Dnmt3A/3L complex and of human DNMT1. The inhibition potency of procainamide conjugated to phtalimide depended on the length of the linker. Such conjugates also showed strong cytotoxicity against two tumour cell lines.

  A straightforward total synthesis of the potent anticancer agent (-)-chaetominine is reported. Central to this synthesis was a biomimetic oxidative cyclization of a tryptophanyl-alanine dipeptide, which provided a fully elaborated 1,2,3,4-tetrahydropyrido[2,3-b]indole. Reduction of this intermediate followed by spontaneous cyclization and installation of the side chain provided synthetic chaetominine

• Cyclomaltooligosaccharide-assisted spectroscopic discrimination of phthalimido-derived amino acids through the formation of molecular aggregates
  作者：Branko S. Jursic、Paresh K. Patel

  DOI：10.1016/j.carres.2006.09.013

  日期：2006.12

  Spectroscopic evidence was used to demonstrate the formation of molecular associates in an aqueous solution of phthalimido tryptophan. These molecular associates are loosely formed through 7r-n aromatic stacking, properties that are not sufficient to cause NMR spectroscopic enantiomeric discrimination. A cyclomaltooligosaccharide with a larger cavity, such as cyclomaltooctaose (gamma-cyclodextrin), is capable of forming a ternary complex with these molecular associates and enhances pi-pi aromatic stacking interactions, resulting in NMR enantiomeric discrimination. Electrospray-ionization mass spectroscopy (ESIMS) and NOESY two-dimensional NMR spectroscopic methods were used to study these complexes. Association constants and thermodynamic data for these cyclomaltooligosaccharide complexes were also estimated. (c) 2006 Elsevier Ltd. All rights reserved.
