Recently I am researching about ONE-POT; TETRAHYDROQUINOLINE DERIVATIVES; BIOLOGICAL EVALUATION; EFFICENT SYNTHESIS; DISPIROHYDROQUINOLINES; QUINOLINE; CATALYST; DESIGN, Saw an article supported by the . Quality Control of 4-Methoxybenzaldehyde. Published in ARKAT USA INC in GAINESVILLE ,Authors: Rui, PX; Xu, ZH; Liu, JL; Huang, QS. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde
An efficient four-component reaction between aromatic aldehydes, 1,3-dioxane-4,6-dione, arylamines and acetone for the synthesis of dispiro[tetrahydroquinoline-bis(1,3-dioxane-4,6-dione)] derivatives in the presence of L-ascorbic acid as an efficient organocatalyst, is described. The remarkable advantages offered by this protocol are an inexpensive catalyst, good yields, a broad substrate scope, mild conditions and, a simple and easy work-up procedure. This method affords the end products through a combination of the Knoevenagel, Michael, Diels-Alder and an intramolecular reaction. [GRAPHICS] .
