account of continuous-flow reaction conditions for biomimeticreductiveamination of fluorinated carbonyl compounds to corresponding amines and amino acids of biomedical importance. We demonstrate that simple silica-adsorbed DBU can be used as efficient catalysts for on-column 1,3-proton shift reaction, a key transformation in the biomimeticreductiveamination process. This new on-column process features
Tetrakis(trimethylsilyl) Ethenylidene-1,1-bisphosphonate: A Mild and Convenient Michael Acceptor for the Synthesis of 2-Aminoethylidene-1,1-bisphosphonic Acids and Their Potassium Salts
A straightforward synthesis of highly functionalized 2-aminoethylidene-1,1-bisphosphonic acids via the Michael addition of amines to easily available tetrakis(trimethylsilyl) ethenylidene-1,1-bisphosphonate, H2C=C[P(O)(OTMS)2]2, has been described. The potassium salts of the title compounds were also easily achieved in high yield by reacting the Michael adducts with potassium fluoride.

The base-catalyzed [1,3]-protonshiftreaction is shown to be an efficient general approach to fluoroalkyl and fluoroaryl amines starting from appropriate carbonyl compounds and benzylamine.
