Silylenolether als 2π-komponenten in (4 + 2)-cycloadditionen: Präparative und kinetische ergebnisse
摘要:
Easily accessible open chain and cyclic silyl enolethers show dienophilic reactivity in (4 + 2)-cycloaddition reactions with inverse electron demand equivalent to enol ethers. Preparative and kinetic results are reported.

The synthesis of the alkylating subunit of the DNA cross-linking agent, isochrysohermidin (2), and its subsequent incorporation into conjugates with distamycin A (1) are described. The DNA binding properties of these agents were compared to that of distamycin A, using a fluorescence intercalator displacement (FID) assay.
