In this practice it is possible to carry out the synthesis of acetaldehyde (ethanal), used as a precursor in the polymerization of plastics, from ethanol and a…
Alternatively, biotin ligase has been used to transfer biotin or a ketone-containing biotin isostere to a 15 amino acid acceptor peptide. Appendage of the ketone isostere allows the formation of hydrazones and oxime conjugates. There is a need for new approaches for site-specific modification of...

Or, I may first condense the halogenated ketone with an aliphatic aldehyde, add the resulting product to a urea-allphatic aldehyde partial condensation product and ...
