Electric Literature of 4265-16-1, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4265-16-1, Name is Benzo[b]furan-2-carboxaldehyde, molecular formula is C9H6O2. In a Article，once mentioned of 4265-16-1
In this paper, we developed facile and high-yield synthetic routes for the preparation of 2-sulfonyl indenes and indanes, including: (i) Amberlyst-15-promoted Knoevenagel reaction of beta-ketosulfones and arylaldehydes in refluxing toluene; (ii) Grignard reagent (R?MgBr) or reducing reagent (NaBH4) promoted regio-and/or stereocontrolled 1,4-Addition or 1,4-/1,2-reduction of the resulting sulfonyl chalcones in THF or MeOH/THF at 25 C; and then (iii) Amberlyst-15 mediated intramolecular Friedel-Crafts annulation of the corresponding beta-ketosulfones or beta-hydroxysulfones in toluene at reflux. This present method describes a highly efficient (3 + 2) annulation via the formation of two carbon-carbon (C-C) bonds. The DFT calculations were utilized to rationalize the regioselectivity of the addition reaction.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4265-16-1, and how the biochemistry of the body works.Electric Literature of 4265-16-1
