“…Rahmatinejad and Naeimi 68 developed a nontoxic and recyclable perovskite-type crumpled LaFeO 3 doped by molybdenum nanosheets as a catalyst which was synthesized using a citric acid-based sol–gel route to provide a one-pot synthesis of naphthopyranopyrimidines 37 via treatment of 26 (1 mmol), various aromatic aldehydes 1 (1 mmol), and 11 / 11a (1 mmol) without solvent at 100 °C ( Scheme 23 ). After the reaction ended, the catalyst was recovered and reused five times without a considerable efficiency loss.…”

The pyranopyrimidine core is a key precursor for medicinal and pharmaceutical industries due to its broader synthetic applications as well as its bioavailability. Among its four possible isomers, we found that 5H-pyrano[2,3-d]pyrimidine scaffolds have a wide range of applicability, and in recent years, they have been intensively investigated, but the development of the main core is found to be more challenging due to its structural existence. In this review article, we cover all of the synthetic pathways that are employed for the development of substituted 4-aryl-octahydropyrano/hexahydrofuro[2,3-d]pyrimidin-2-one (thiones) and 5-aryl-substituted pyrano[2,3-d]pyrimidindione (2-thiones) derivatives through a one-pot multicomponent reaction using diversified hybrid catalysts such as organocatalysts, metal catalysts, ionic liquid catalysts, nanocatalysts, green solvents, catalyst-/solvent-free conditions, and miscellaneous catalysts as well as the mechanism and recyclability of the catalysts. This review mainly focuses on the application of hybrid catalysts (from 1992 to 2022) for the synthesis of 5H-pyrano[2,3-d]pyrimidine scaffolds. This review will definitely attract the world’s leading researchers to utilize broader catalytic applications for the development of lead molecules.

“…This procedure offers fascinating benefits, including smooth status, low reaction period, avoidance of solid acid media, little catalyst loading, convenient work-up and simple purification of products, high thermal stability, and catalyst reusability at least five successive runs without a notable change in its attribute. 94 The preparation of perovskite-type LaMo 0 . 1 Fe 0 .…”

“…After drying the gel, LaFeO 3 nanocatalyst was achieved by calcinating the dry gel at 620 C for 2 h. In the second way, after evaporating the resulting sol, the formed compound was pre-calcined in an oven at 400 C for 2 h and then calcined at 750 C (3 h) in the air to give the LaFeO 3 perovskites phase (Scheme 96). 94 The two plausible mechanisms for synthesizing naphthopyranopyrimidines 97 using perovskite-type LaMo 0 . 1 Fe 0 .…”

Heterocycles and barbituric acid analogs are particularly used in developing and designing new drugs because of their versatile binding properties for different biotargets. They are present in many natural compounds, vitamins, drugs, and biologically active molecules such as anticancer, antibiotic, antidiabetic, anti‐inflammatory, antidepressant, anti‐HIV, antimicrobial, and insecticidal agents. Using co‐friendly techniques under nanocatalyst conditions drives the synthesis of these bioactive compounds toward green chemistry. This review will investigate the nanocatalysts, including magnetic nanocatalysts, nano metal‐based catalysts, organo‐nanocatalysts, and metal–organic frameworks (MOFs) nanocatalysts employed in the synthesis and design of heterocyclic compounds by barbituric acids from 2017 to 2022.

“…Rahmatinejad, and Naeimi, 124 have employed the utility of molybdenum-doped LaFeO 3 nano-sheets (8 mol%) as an effective catalyst for the synthesis of naphthopyranopyrimidine 53a–q. Thus, following the same previous reaction sequence of the reactants, β-naphthol reacted with aryl aldehydes, and (thio)barbituric acids in a one-pot multicomponent procedure under catalytic, free-solvent, and heating conditions giving the appraised naphthopyranopyrimidine derivatives 53a–q in 82–92% yields.…”
