• Oxazolinethiones and Oxazolidinethiones for the First Copper-Catalyzed Desulfurative Cross-Coupling Reaction and First Sonogashira Applications

  chiral oxazolidinethiones (OZT) and aromatic oxazolinethiones (OXT), were involved, for the first time, in Sonogashira cross-coupling. A cooperative effect of two different copper (I) species-CuI and CuTC-accounts for this new copper-catalyzed desulfurative carbon-carbon cross-coupling reaction. This cooperative reactivity could also be extended to other copper (I) catalysts.

• Synthesis, characterization and X-ray structure of glycosyl-1,2-isoxazoles and glycosyl-1,2-isoxazolines prepared via 1,3-dipolar cycloaddition

  A convenient preparative method of a series of glycosyl-1,2-isoxazoles (6-11) and glycosyl-1,2-isoxazolines (15-20) by a simple and efficient 1,3-dipolar cycloaddition of a series of aryl nitrile oxide, generated in situ from aryl oximes (4-5), with a variety of O-propargyl glycosyles (1-3) or O-allyl glycosyles (12-14) respectively, is reported. The carbohydrate-containing 1,2-isoxazoles and 1,2-isoxazolines compounds were isolated in excellent yields (81-91%) and they were fully characterized by H-1, C-13 NMR and mass spectrometry. The relative stereochemistry of the glycosyl-1,2-isoxazole 10 was confirmed by single crystal X-ray analysis. The molecular structure of 10 confirms the retention of both, the anomeric stereochemistry of the D-fructose as well as the placement of the acetal groups. (c) 2013 Elsevier B.V. All rights reserved.

• Asymmetric Pd/Organoboron‐Catalyzed Site‐Selective Carbohydrate Functionalization with Alkoxyallenes Involving Noncovalent Stereocontrol
  作者：Hao Guo、Jan‐Lukas Kirchhoff、Carsten Strohmann、Bastian Grabe、Charles C. J. Loh

  DOI：10.1002/anie.202400912

  日期：2024.5.21

  Herein, we demonstrate the robustness of a synergistic chiral Pd/organoboron system in tackling a challenging suite of site‐, regio‐, enantio‐ and diastereoselectivity issues across a considerable palette of biologically relevant carbohydrate polyols, when prochiral alkoxyallenes were employed as electrophiles. In view of the burgeoning role of noncovalent interactions (NCIs) in stereoselective carbohydrate synthesis, our mechanistic experiments and DFT modeling of the reaction path unexpectedly revealed that NCIs such as hydrogen bonding and CH‐π interactions between the resting states of the Pd‐π‐allyl complex and the borinate saccharide are critically involved in the stereoselectivity control. Our strategy thus illuminates the untapped potential of harnessing NCIs in the context of transition metal catalysis to tackle stereoselectivity challenges in carbohydrate functionalization.
