Abstract Streamline synthesis of cyclic alcohols has been an enduring goal in synthetic chemistry. In this regard, a series aminoquinoline‐based pincer ligands (L1(H)=2‐(dimethylamino)‐ N ‐(quinolin‐8‐yl)acetamide, L2(H)=2‐(diethylamino)‐ ‐(quinoline‐8‐yl)acetamide, L3(H)=2‐(dipropylamino)‐ ‐(quinoline‐8‐yl)acetamide and L4(H)=2‐(dibutylamino)‐ ‐(quinolin‐8‐yl)acetamide)) corresponding nickel(II) complexes the type [Ni(L)Cl] ( 1–4 ) were synthesized characterized using modern analytical techniques. Further, catalytic activity 1 – 4 was investigated for oxidation cyclohexane presence different oxidants. All catalysts showed substantial m ‐CPBA as oxidant DCM‐CH 3 CN (v/v, : 1) solvent mixture at 60 ° C to yield cyclohexanol major product cyclohexanone caprolactone minor products. Under optimised reaction conditions, order (936)> 2 (892)> (835)> (785), which can be rationalized by steric‐electronic properties respective ligands. Notably, with catalyst , we could achieve highest TON (936) reported so far having square planar geometry. The best catalyst, further used other cycloalkanes appreciable activity. formation chlorinated products distribution pattern revealed that is mediated majorly 3‐chlorobenzoyloxy radical.

Elaborated molecular architectures, specifically those containing a 2-aminophenoxazinone scaffold, belong to one of the most ubiquitous and prominent classes heterocyclic frameworks, going from natural products biologically active pharmaceutical molecules agrochemicals functional materials polymers. Therefore, efficient synthetic strategies for assembly frameworks are always in demand have gained attention academic industrial communities. Methodologies that involve cascade reactions generally catalyzed by transition metal complexes, such as iron, cobalt, manganese, copper, zinc stood out representative approach. Over past few decades, great deal versatile, atom-economic, straightforward protocols been reported generation value-added sustainable, powerful, applicable manner. The state-of-the-art methodologies toward construction skeletons summarized this review, which could be divided into four categories: (1) compounds complexes; (2) biosynthetic enzymes; (3) process routes compounds; (4) via other innovative methods.
