A new synthetic strategy for heteroanthracyclines: Total synthesis of D-ring thiophene analogs of daunomycin

The strong base-induced cycloaddition of appropriately functionalized thiophene analogs of homophthalic anhydride constitutes a highly regiospecific and convenient route to the D-ring thiophene analogs (2 and 3) of daunomycin.

Strong base induced cycloaddition of 3-carboxy-1-methylindole-2-acetic anhydride and 2-carboxybenzo[b]furan-3-acetic anhydride: synthesis of polycyclic peri-hydroxylated indole and benzofuran compounds

Abstract Generation of indole- and benzofuran-2,3-orthoquinodimethane-like intermediates is described. The cycloaddition reaction of these intermediates to dienophiles provided an efficient one-pot synthesis of polycyclic perihydroxylated indole and benzofuran compounds.

Regio- and stereo-chemical aspects of [2 + 2] photocycloaddition between 1-benzoylindoles and olefins

The regio- and stereo-selectivities in the [2 + 2] photocycloaddition of a series of 1-benzoylindoles with vinyl acetate and methyl acrylate have been investigated. With some exceptions, the 1 -benzoylindoles gave exclusively or predominantly the corresponding 1-acetoxy-3-benzoyl and 3-benzoyl-1-methoxycarbonyl-1,2,2a,7b-tetrahydro-3H-cyclobut[b]indoles as mixtures of stereoisomers.
