In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Sulfur derivatives in the pyrrole series, published in 1973, which mentions a compound: 2199-44-2, mainly applied to pyrrolyl sulfide; thiocarboxamide pyrrole, Synthetic Route of C9H13NO2.
Reaction of 2,4-dimethyl-5-(ethoxycarbonyl)pyrrole (I) with SO2 in the presence of EtBr and AlCl3 or in CH2Cl2 containing AlCl3 gave the sulfide II or the sulfoxide III, resp. Successive reaction of SCl2 with MeOH and 2-methyl-3-(ethoxycarbonyl pyrrole gave the disulfide IV. Addition of EtSH to tris[2-methyl-3-(ethoxycarbonyl)-5-pyrrolyl]methane gave the sulfide V. Addition of p-tolysulfonyl isothiocyanate to I gave the derivative VI.
From this literature《Sulfur derivatives in the pyrrole series》,we know some information about this compound(2199-44-2)Synthetic Route of C9H13NO2, but this is not all information, there are many literatures related to this compound(2199-44-2).
