Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Dalinger, IL, once mentioned the application of 555-16-8, Name is 4-Nitrobenzaldehyde, molecular formula is C7H5NO3, molecular weight is 151.12, MDL number is MFCD00007346, category is isothiazole. Now introduce a scientific discovery about this category, Recommanded Product: 555-16-8.
Regioselectivity of the substitution for the nitro group in 2,4,6-trinitrobenzonitrile under the action of thiols. The synthesis of 4,6-dinitro derivatives of benzo-annelated sulfur-containing heterocycles
Conditions for the regioselective substitution for a nitro group in the ortho-position in 2,4,6-trinitrobenzonitrile under the action of thiols (PhCH2SH, HSCH2CO2Et or PhSH) in the presence of K2CO3 or KOH were found, and the intramolecular cyclization of the ortho-fragments -SX and -CN (X = Cl or CH2CO2Et) was performed to afford 3-chloro-4,6-dinitrobenzo[d]isothiazole and 3-amino-2-ethoxycarbonyl-4,6-dinitrobenzo[b]thiophene, respectively.
