The present invention relates to linkers having a group of propiolyl, substituted acryl (acryloyl), or disubstituted propanoyl, and using such linkers for the conjugation of compounds, in particular, cytotoxic agents to a cell-binding molecule.
A Versatile Synthesis of N Carboxy-α,β-didehydro-α-amino Acid Anhydrides (4-Alkylidene-2,5-oxazolidinediones) α-Azidocarboxylic acids 1 react with phosgene in the presence of catalytic amounts of sodium perrhenate in dimethoxyethane at 85°C to give N-carboxy-α,β-didehydroamino acid anhydrides (4-alkylidene-2.5-oxazolidinediones) 2 in good yields.

worldwide concern, prompting the urgent development of new effective treatments for antibiotic resistant bacterial infections. Harnessing the benefits of multivalency and cooperativity against vancomycin‐resistant strains, we report a Click Chemistry approach towards reengineered vancomycin derivatives and the synthesis of a number of dimers with increased potency against MRSA and vancomycin resistant

The present invention provides methods and compositions for expanding the scope of chemical reactions that can be performed during nucleic acid-templated organic syntheses. In particular, nucleic acid-templated chemistries are used to produce reaction intermediates attached to an oligonucleotide that can be used to identify the reaction intermediates and/or the resulting reaction products. The reaction intermediates then are reacted with free reactants (for example, reactants that are difficult or impractical to couple to an oligonucleotide) to produce a reaction product. This approach expands the scope of reagents useful in nucleic acid-templated syntheses to reagents that do not need to be or cannot be tethered to an oligonucleotide. The reagents, however, still permit the synthesis of reaction products attached to oligonucleotides that can be used to identify the reaction products.
