: This review collects for the first time enantioselective one-pot processes promoted by green chiral zinc catalysts. It illustrates how much these cheap, non-toxic and environmentally benign catalysts allow unprecedented asymmetric domino and tandem reactions of many types to be achieved, allowing a direct access to a wide variety of very complex chiral molecules.

It is promising and challenging to achieve the effective construction of carbonates using CO2 and a non-noble metal catalyst. Herein, selective catalytic conversion of CO2 and switchable alcohol candidates to produce linear or cyclic carbonates and α-hydroxy ketones via effective zinc catalyst was developed. A series of primary alcohols and cyclohexanol, 1,2-diols, and water can serve as nucleophiles to give alkyl or aryl 2-substituted-3-oxobutan-2-yl carbonates, substituted 1,3-dioxolan-2-ones, 3-substituted 3-hydroxybutan-2-ones, respectively with excellent selectivity and high yields.

The scaffolds having 1H-Pyrrolo[3,2-c]pyridine core show significant biological activity. Herein, we report a synergetic copper/zinc-catalyzed one-step annulation reaction of 2-amino (hetero)arylnitriles with ynamide-derived buta-1,3-diynes to deliver 1H-pyrrolo[3,2-c]quinoline-2,4-diamine derivatives in moderate...
