Category: esters-buliding-blocksIn 2021 ,《A supramolecular double-helix based on complementary phosphate-guanidinium pairing》 was published in Chemical Communications (Cambridge, United Kingdom). The article was written by Thiele, Maike; Octa-Smolin, Frescilia; Thoelke, Simon; Woelper, Christoph; Linders, Juergen; Mayer, Christian; Haberhauer, Gebhard; Niemeyer, Jochen. The article contains the following contents:
A double-helical supramol. structure was formed by self-assembly of 1,1′;-binaphthyl-based bisguanidines and bisphosphoric acids. Interestingly the homochiral (S,S) + (S,S)-pair forms a left-handed double-helix, while the heterochiral (S,S) + (R,R)-pair forms a non-helical dimer. The results came from multiple reactions, including the reaction of tert-Butyl carbamate(cas: 4248-19-5Category: esters-buliding-blocks)
tert-Butyl carbamate(cas: 4248-19-5) belongs to anime.Typically the presence of an amine functional group is deduced by a combination of techniques, including mass spectrometry as well as NMR and IR spectroscopies. 1H NMR signals for amines disappear upon treatment of the sample with D2O. In their infrared spectrum primary amines exhibit two N-H bands, whereas secondary amines exhibit only one.Category: esters-buliding-blocks
