Summary: Gold catalysis has been a significant breakthrough in organic synthesis due to its tunable nature, unique properties, and mild reaction conditions. Despite its popularity, gold-catalyzed reactions still face limitations such as low turnover numbers. Optimizing catalysts and reaction conditions may enhance the efficiency of gold-catalyzed reactions. This review focuses on examples of counterion or additive-regulated gold catalysis from a mechanistic perspective, highlighting the impact of physical properties on gold catalyst reactivity.

Summary: A gold(i)-catalyzed intramolecular cyclization reaction was developed to synthesize functionalized morpholines, piperazines, and oxazepanes. The reaction proceeds via a carbene or non-carbene process and exhibits a broad substrate scope, good functional group tolerance, and mild reaction conditions. The reaction pathway can be modulated by the steric bulkiness or chain length of the substrate.

Summary: This paper presents the first report on the intramolecular [2+2] cycloaddition of vinylsilane. Previous studies have focused on controlling regioselectivity in the [2+2] cycloaddition of allenes by changing the substrate, but no research has attempted to achieve this solely by altering the reaction conditions. In this study, we successfully controlled the intramolecular [2+2] cycloaddition at proximal and distal positions of allenes by modifying the reaction conditions.

Summary: The combination of gold(I) and enzyme catalysis in a two-step approach was used to synthesize optically pure beta,beta-disubstituted allylic alcohols. The cascade reaction involves a gold N-heterocyclic carbene and an enzyme in aqueous medium under mild conditions, leading to good yields of optically active compounds. This method was extended to various derivatives and the use of alcohol dehydrogenases with opposite selectivity allowed for the production of enantiomers of allyl alcohol.

Summary: Sulfonated-silica-coated cobalt ferrite magnetic nanoparticles (MNPs-SiCoFe-SO3H) are efficient heterogeneous catalysts for the synthesis of 3,4-dihydropyrimidin-2(1H)-one and octahydroquinazoline derivatives in the absence of solvent. The effects of solvent, temperature, and catalyst amount on the reaction were investigated. This method offers advantages such as easy separation, reusability of the catalyst, simplicity of the procedure, mild reaction conditions, and good yields (68-95%) within short reaction times (15-70 min). The catalyst can be reused up to eight times with minimal loss of activity, as evidenced by scanning electron microscopy images, X-ray diffraction spectra, and elemental analysis of the recycled catalyst.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
