Tandem Dehydrogenation/Oxidation/Oxidative Cyclization Approach to Wrightiadione and Its Derivatives
摘要:
Wrightiadione contains a unique tetracyclic isoflavone moiety and has been shown to exhibit a broad range of biological activities. An efficient and Straightforward synthetic method for generating the molecular complexity,of wrightiadione was developed, through three-step tandem dehydrogenation/oxidation/oxidative cyclization reactions with a Pd/Cu. catalytic system. This Unprecedented one-pot route utilizes a broad: range of substrates, providing a convenient and powerful synthetic tool for accessing naturally occurring tetracyclic isoflavone wrightiadione and its nitrogen-containing derivatives.

Synthesis of a recently discovered S-methylated quinolone natural product (1) was carried out, in addition to the production of a range of 2-substituted 4-quinolone derivatives (2–11). Two approaches were used: (i) the base-catalyzed cyclization of N-(ketoaryl)amides; (ii) attachment of the substituent to the quinolone core via a Suzuki–Miyaura cross-coupling. Also produced were a small suite of related
