  摘要：

  An extension of the Vorbruggen method of nucleotide synthesis for the synthesis of G glucopyranosides, as intermediates for C-nucleosides, is described. It could be shown that the diastereoselectivity of the reaction can be tuned by a simple change of protecting groups.

  Methods of using NMR spectroscopy for identifying ligands that bind to structurally uncharacterized proteins, and for improving the binding affinity of ligands for biological targets, which in one aspect comprises: a) preparing first NMR spectra of a first complex comprising the biological target and a paramagnetically labeled derivative of a first ligand; b) preparing second NMR spectra of a second complex comprising the biological target and a second ligand; and c) analyzing the spectra to determine whether the second ligand binds to the biological target within the paramagnetic zone of the paramagnetically labeled derivative; wherein steps (a) and (b) are performed simultaneously, consecutively, or in any order.

• Design of Chiral Auxiliaries for the Allene Ether Nazarov Cyclization

  日期：2007.5.1

  A 1,3- or a 1,4-cis axial tert-butyldimethylsilyloxy substituent on the pyranose derived chiral auxiliary for the allene ether Nazarov cyclization leads to products in high optical purity. alpha-Pyranose and beta-pyranose derived auxiliaries lead to enantiomeric products.
• Simple Designs for the Construction of Complex trans-Fused Polyether Toxin Frameworks. A Linear Strategy Based on Entropically Favored Oxirane Ring Enlargement in Epoxycycloalkenes Followed by Carbon-Carbon or Carbon-Oxygen Bond-Forming Cyclizations

  A successful design for the construction of trans-fused medium-size cyclic ethers is described. The key features of the synthesis are as follows: (i) intramolecular oxirane ring expansion in cycloalkenes to give bridged oxabicyclic systems and (ii) linear, one- or two-directional synthetic operations which generate external oxocycles in single reaction steps. The general approach involves the intramolecular addition of a stable gamma-alkoxy-substituted allylstannane to an aldehyde carbonyl group, and the entire reaction is conducted in a one-pot process which includes the following: (i) vic-diol fragmentation from the bridged oxabicyclic precursor and (ii) Lewis acid-induced cyclization of the resulting aldehyde-allylic tin system. While the present strategy was mostly developed around racemic models, the potential for adoption of;enantioselective features is immediate. The versatility, scope, limitations, and potential applications of the present technology are discussed in detail.
