Sauter, F. et al. published their research in Scientia Pharmaceutica in 1996 | CAS: 70291-62-2

2-Amino-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile (cas: 70291-62-2) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).HPLC of Formula: 70291-62-2

Reagents for new heteroannelation reactions. Part I. Isocyanate-dithioketal reagents was written by Sauter, F.;Froehlich, J.;Shaifullah Chowdhury, A. Z. M.. And the article was included in Scientia Pharmaceutica in 1996.HPLC of Formula: 70291-62-2 This article mentions the following:

(MeS)2C:NCH2CO2Et was reacted with various educts. While heteroaromatic 2-amino esters gave cyclization to a pyrimido moiety, the corresponding 2-amino nitriles led in 1-pot reactions to double-annelation, yielding products with an imidazopyrimido moiety. In the experiment, the researchers used many compounds, for example, 2-Amino-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile (cas: 70291-62-2HPLC of Formula: 70291-62-2).
