Formula: C7H6O2In 2020 ,《An Organocatalytic Newer Synthetic Strategy Toward the Access of Polyfunctionalized 4H-Pyrans via Multicomponent Reactions》 appeared in Polycyclic Aromatic Compounds. The author of the article were Ramesh, Rathinam; Jayamathi, Jayaraj; Karthika, Chinnagoundar; Malecki, Jan Grzegorz; Lalitha, Appaswami. The article conveys some information:
An energy efficient, facile, and environmentally benign synthetic method to obtain pharmaceutically fortunate, diverse 4H-pyrans from frequently accessible aryl aldehydes, malononitrile, and dissimilar 1,3-diketoesters is described. The reactions took place smoothly at ambient temperature using 2-aminopyridine as a low-cost organocatalyst. The present domino strategy furnishes, the desired products in high yields with shorter reaction times. The structures of the o-nitro substituted skeletons were unambiguously confirmed by mono-crystal XRD. The results came from multiple reactions, including the reaction of 3-Hydroxybenzaldehyde(cas: 100-83-4Formula: C7H6O2)
3-Hydroxybenzaldehyde(cas: 100-83-4) is used as an ionophore, during the development of an highly selective and sensitive PVC membrane sensor, which can be used as a Tb3+ ion selective electrode.Formula: C7H6O2
