An efficient approach to the BCD ring system of the penitrems"^^ . "(Matrix presented) Radical/polar crossover reactions of derivatives of 1-(2-cyclobutenyl)-2-(2-iodoaryl)ethanones with acetone promoted by samarium diiodide and HMPA provide 1-(1-hydroxy-1-methylethyl)-2,2a,4,8b-tetrahydro-1H-cyclobuta[a] naphthalen-3-one derivatives in about 50% isolated yield. This reaction shows promise for construction of the BCD ring fragment of the penitrems."^^ . "2003-02-20" . . "5" . "4" . . "Organic Letters"^^ . . . "15237060" . . . . . . . . . . . . . "DP"^^ .
