All molecules in this space are feasible for synthesis with high predicted success rate, since their enumeration is based on previously acquired validated experimental data. Additionally, custom synthesis of specific core-structures for the Customer’s needs are also possible and could be performed on both FFS and FTE base. Our team of experienced Synthetic Organic Chemists can deliver new desired molecules at competitive prices in short lead time. The on-DNA synthesis of functionally diverse pyridazines based on inverse-electron-demand Diels-Alder (IEDDA) reactions of 1,2,4,5-tetrazines has been shown recently. Herein we propose tetrazine-derived compound library designed for DNA ligation and DNA-compatible IEDDA reactions.
