Diazonamide Synthesis Studies: Use of Negishi Coupling to Fashion Diazonamide-Related Biaryls with Defined Axial Chirality
摘要:
[GRAPHICS]The syntheses of a bis indole and an indole salicylate with the required axial chirality for diazonamide A are reported. Atropselectivity in these biaryl systems is enforced by an sp(3) stereogenic center in a lactone tether in both cases.
