Abstract :

This talk covers our work about new methodologies developed in our laboratory regarding unusual amino acid derivatives. During the past couple of decades our group has engaged in design and synthesis of unusual amino acid derivatives and peptides. We have used modern synthetic strategies to prepare the required amino acid based building blocks and modified peptides. Some of these include enyne metathesis, cross-metathesis, Suzuki coupling, Diels-Alder reaction, [3+2] cycloaddition and [2+2+2] cyclotrimerization. In addition, we have also used rongalite as a useful green reagent for the preparation of benzosultine derivatives, which are the latent precursors to o-xylylene intermediates. These advances in designing new methodologies will impact the synthesis of modified amino acid derivatives and peptides and ultimately in drug discovery process.
