Stereoselective construction of a variety of β-glycosides can be achieved using abundant and inexpensive KCO-mediated stereoselective anomeric O-alkylation of sugar lactols with primary electrophiles. In addition, application of this methodology to the synthesis of various azido-modified glycosphingolipids has been accomplished in good yields and excellent anomeric selectivity using sphingosine-derived primary triflate.

Ni-catalyzed asymmetric reductive cross-coupling reactions provide rapid and modular access to enantioenriched building blocks from simple electrophile precursors. Reductive coupling reactions that can diverge through a common organometallic intermediate to two distinct families of enantioenriched products are particularly versatile but underdeveloped. Here, we describe the development of a bis(oxazoline) ligand that enables the desymmetrization of -anhydrides.

Herein, we report a Ni-catalyzed cross-electrophile coupling of aryl/vinyl halides with benzothiazolium salts derived from alcohols. Our findings demonstrate that primary alkyl benzothiazolium salts serve as effective C(sp)-O substrates, facilitating coupling with aryl and vinyl halides. This method not only enables the formal functionalization of primary alcohols but also provides experimental support for previously established sequential alcohol halogenation and Ni-catalyzed reductive coupling platforms.

In view of the high propensity of tertiary alkyl amines to be bioactive, the development of new methods for their synthesis is an important challenge. Transition-metal catalysis has the potential to greatly expand the scope of nucleophilic substitution reactions of alkyl electrophiles; unfortunately, in the case of alkyl amines as nucleophiles, only one success has been described so far: the selective mono-alkylation of primary amines to form secondary amines. Here, using photoinduced copper catalysis, we report the synthesis of tertiary alkyl amines from secondary amines and unactivated alkyl electrophiles, two readily available coupling partners.

The presence of redox-active molecules containing catenated sulfur atoms (supersulfides) in living organisms has led to a review of the concepts of redox biology and its translational strategy. Glutathione (GSH) is the body's primary detoxifier and antioxidant, and its oxidized form (GSSG) has been considered as a marker of oxidative status. However, we report that GSSG, but not reduced GSH, prevents ischemic supersulfide catabolism-associated heart failure in male mice by electrophilic modification of dynamin-related protein (Drp1).

Unsymmetric disulfides are prevalent in natural products and are essential in medicinal chemistry and materials science, but their robust synthesis poses significant challenges. In this paper, we report an expeditous transition-metal-free methodology for synthesizing unsymmetric disulfides through the addition of perthiyl radicals to alkenes. This study marks the use of generating perthiyl radicals by reacting SO with unactivated alkyl (pseudo)halides (Cl/Br/I/OTs).
