Abstract:
The development of photoenzymatic non-natural reactions facilitates the synthesis of challenging high-value-added chiral compounds. However, this approach typically requires enzyme engineering to enhance both the catalytic activity and selectivity. Herein, we report a synergistic photoenymatic system comprising wild-type GluER and exogenous Ru(bpy)3Cl2·6H2O that enables the photoenzymatic enantioselective hydroalkylation of olefins. In this system, Ru(bpy)3Cl2·6H2O replaces protein engineering, driving an efficient catalytic cycle. The radical initiation was by electron transfer between excited Ru(bpy)3Cl2·6H2O and an in situ-formed ternary electron donor-acceptor (EDA) complex. This synergistic photo/biocatalytic system decreases the time-consuming and labor-intensive nature while providing an environmentally friendly methodology for chemical synthesis.

Preparation of Amides
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
