Published: June 2012

In this communication, we document a facile kinetic glycosylation resolution of racemic tetrahydroberberrubine. We also demonstrate that the enantiomeric excess of the resolved products is increased via a second resolution of the minor product of the first glycosylation resolution. This provides a rare example of tandem kinetic resolution of racemates.

ConspectusSymmetry is a pervasive phenomenon spanning diverse fields, from art and architecture to mathematics and science. In the scientific realms, symmetry reveals fundamental laws, while symmetry breaking─the collapse of certain symmetry─is the underlying cause of phenomena. Research on symmetry and symmetry breaking consistently provides valuable insights across disciplines, from parity violation in physics to the origin of homochirality in biology.

Nucleoside derivatives having a 4-substituent show promise as potential antiviral agents as well as nucleoside units for constructing nucleic acid medicines. To develop new nucleosides, it is crucial to achieve feasible access to the intended derivatives, encompassing both enantiomers. Toward this end, we started synthesizing an achiral 4-hydroxymethyldihydrofuran as a sugar precursor, which we subjected to the oxidative glycosylation reaction using hypervalent iodine.

ConspectusChiral organosilicon compounds bearing a Si-stereogenic center have attracted increasing attention in various scientific communities and appear to be a topic of high current relevance in modern organic chemistry, given their versatile utility as chiral building blocks, chiral reagents, chiral auxiliaries, and chiral catalysts. Historically, access to these non-natural Si-stereogenic silanes mainly relies on resolution, whereas their asymmetric synthetic methods dramatically lagged compared to their carbon counterparts. Over the past two decades, transition-metal-catalyzed desymmetrization of prochiral organosilanes has emerged as an effective tool for the synthesis of enantioenriched Si-stereogenic silanes.

The synthesis of chiral tetrahydroquinolines (THQs) has garnered significant interest from medicinal chemists due to their frequent presence as pharmacophores in bioactive compounds. While existing synthetic methods have primarily focused on THQs with single or multiple endocyclic chiral centers, the selective construction of THQs with both and cyclic chiral centers remains a significant challenge that requires further development. This study introduces a dynamic kinetic resolution (DKR)-based transfer hydrogenation of racemic 2-substituted quinolines, which yields structurally novel chiral THQs with consecutive and cyclic chiral centers in excellent yields and stereoselectivities (59 examples, with generally >20:1 dr and >90% ee, up to three consecutive stereocenters).

The development of efficient immobilization support for the enhancement of enzyme activity and recyclability is a highly desirable objective. Single-crystalline ordered macro-microporous ZIF-8 (SOM-ZIF-8), has emerged as a highly effective matrix for enzyme immobilization, however, the inherent hydrophobic nature limits its further advancement. Herein, we have customized the immobilization of the Pseudomonas cepacia lipase (LP) in the modification-channels of SOM-ZIF-8 by functionalizing the inner surface-properties with polyethylene glycol (PEG) (LP@SOM-ZIF-8-PEG), and significant enhancement of the activity and (thermal, solvent and cyclic) stability can be realized.
