General Description

Dimethyl 2-(2-Nitrophenyl)malonate, also known as NSC 55503 or AC1LDA4Y, is a chemical compound with the formula C12H13NO6. It falls under the categories of malonates and dicarboxylates. The chemical, distinguished by its bright yellow appearance, is often used in scientific laboratory research. Despite its common usage, there is limited information available regarding its exact potency or toxicity, making it necessary to handle with caution. Its synthesis involves nitrophenyl and malonic acid with methanol and nitric acid in methylating, nitrating, and condensing actions. It’s important for research related to carbon-carbon bond formations.

A Unified Catalytic Asymmetric (4+1) and (5+1) Annulation Strategy to Access Chiral Spirooxindole-Fused Oxacycles

A unified catalytic asymmetric (N+1) (N=4, 5) annulation reaction of oxindoles with bifunctional peroxides has been achieved in the presence of a chiral phase-transfer catalyst (PTC). This general strategy utilizes peroxides as unique bielectrophilic four- or five-atom synthons to participate in the C?C and the subsequent umpolung C?O bond-forming reactions with one-carbon unit nucleophiles, thus providing a distinct method to access the valuable chiral spirooxindole-tetrahydrofurans and -tetrahydropyrans with good yields and high enantioselectivities under mild conditions. DFT calculations were performed to rationalize the origin of high enantioselectivity. The gram-scale syntheses and synthetic utility of the resultant products were also demonstrated.
