Application

Dimethylamine can be used:
  • In the preparation of 1-organyl-1-(trimethylsiloxy)-2-(dimethylamino)ethenes starting from α-bromo ketones.
  • In one of the key synthetic steps for the preparation of 1-methoxycarbonylpyrrolizin-3-one and its associated compounds.
  • Ni-catalyzed cross-electrophile coupling of Katritzky pyridinium salts with bromoalkanes through C-N bond activation.
  • To synthesize tertiary amides which on reaction with Petasis reagent followed by bromination forms bromomethyl ketones.

Analysis of protein glycosylation is an important first step towards establishing the functions of glycans in health and disease. In contrast to N-glycans which are generally enzymatically released for analysis, there is no corresponding enzyme for O-glycan liberation. Therefore, O-glycans...
