α-Oxoketenes and cyclohexadiene α-oxoketenes are reactive intermediates, particularly the latter due to their high re-aromatization potential. In this communication, we report photolytic studies on the generation of such species from 4-OMe and 4-OMOM protected resorcylate dioxinones and their trapping to give resorcylate esters and amides as well as the formation of adducts with enol-ethers as trapping reagents.
SYNTHESES OF 4-HYDROXY-5-IODO-2,3-DIMETHOXY-6-METHYLBENZOIC ACID AND 5-BROMO-4-HYDROXY-2,3-DIMETHOXY-6-METHYLBENZOIC ACID - AROMATIC CONSTITUENTS OF THE CALICHEMICINS
