Derivatives of 2,3,5,6,7,7a-hexahydro-1,3-dioxo-1H-pyrrolo[1,2-c]imidazole-5-carboxylic acids was written by Fontanella, L.;Corsico, N.;Diena, A.;Occelli, E.. And the article was included in Farmaco, Edizione Scientifica in 1984.SDS of cas: 16413-26-6 This article mentions the following:
1-Carbamoylpyrrolidines I (R = Ph, tolyl, anisyl, halo-, nitro-, or cyanophenyl) were converted to pyrroloimidazolecarboxamides II (R1 and R2 are H, alkyl, or NR1R2 = pyrrolidino), which showed anxiolytic activity. I (R = Ph) was heated with HCl to give acid III, and III was treated with ClCO2Et, Et3N, and NH3 to give II (R = Ph, R1 = R2 = H). In the experiment, the researchers used many compounds, for example, 3-Cyanophenylisocyanate (cas: 16413-26-6SDS of cas: 16413-26-6).
3-Cyanophenylisocyanate (cas: 16413-26-6) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.SDS of cas: 16413-26-6
