Silyanova, Eugenia A. published the artcileFormation of 3,4-Diarylpyrrole- and Pyrrolocoumarin Core of Natural Marine Products via Barton-Zard Reaction and Selective O-Demethylation, COA of Formula: C9H10O3, the main research area is diarylpyrrole pyrrolocoumarin lamellarin core preparation Barton Zard selective demethylation.
A metal-free approach to 3,4-diarylpyrrole-2-carboxylate and pyrrolocoumarin cores of lamellarins and related natural products based on Barton-Zard reaction of nitrostilbenes with Et isocyanoacetate was developed. In the case of diarylpyrrole-2-carboxylates with a 3-(o-methoxyphenyl) fragment, treatment with 1 equivalent of BBr3 resulted in selective O-demethylation of the ortho-methoxy group, while other methoxy groups in the mol. remained intact. The resulting 3-(2-hydroxyphenyl)pyrrole-2-carboxylates underwent base-induced lactonization to form the target pyrrolocoumarins.
European Journal of Organic Chemistry published new progress about Alkaloids Role: SPN (Synthetic Preparation), PREP (Preparation) (lamellarins). 86-51-1 belongs to class isoquinoline, name is 2,3-Dimethoxybenzaldehyde, and the molecular formula is C9H10O3, COA of Formula: C9H10O3.
