The synthesis of the model compound of kinamycin antibiotics, which possesses correct relative configurations at C(1)C(4) on the D-ring, is reported. The key steps involve a Diels–Alder reaction of an indenone and a Danishefsky-type diene, and stereoselective construction of a tetraoxygenated D-ring.
model compound of kinamycin antibiotics, which possesses correct relative configurations at C1–C4 on the D ring, is reported in detail. The key steps involved a Diels–Alder reaction of indenone (12) and a Danishefsky-type diene (13), and stereoselective construction of a tetraoxygenated D ring.
