Abstract
Synthesis of benzo [d] naphtho [1, 2-b] pyran-6-one furanoid C-glycosides, related to the gilvocarcin, ravidomycin, and chrysomycin class of antibiotics, has been accomplished by regio-and stereospecific coupling of a furanoid glycal, 1, 4-anhydro-2-deoxy-5-0- (methoxymethyl)-3-0-[tris (l-methylethyl) silyl]-~-erythro-pent-l-enitol with tri-n-butylstannyl derivatives of benzo [d] naphtho [1,241 pyran-6-0nes in the presence of stoichiometric ...
