  A concise synthesis of 3,4-fused spiro[isobenzofuran-3-ones], spiro[furo[3,4- b ]pyridin-5(7 H )-ones], 3-aryl-, and alkylphthalides

  摘要：

  A synthetically useful protocol has been developed for the preparation of highly functionalized 3,4-fused spiro[isobenzofuran-3-ones], spiro[furo[3,4-b]pyridin-5(7H)-ones], 3-aryl-, and alkylphthalides. Reaction of 2-iodobenzoate esters and 2-iodopyridine carboxylate esters with i-PrMgCl center dot LiCl in the presence of cyclic ketones under standard Barbier reaction conditions affords 3,4-fused spiro[isobenzofuran-3-ones] and spiro[furo[3,4-b]pyridin-5(7H)-ones] in good to excellent yields. Step-wise addition of i-PrMgCl center dot LiCl to 2-iodobenzoate esters followed by trapping with various aldehydes yields 3-aryl and 3-alkylphthalides; whereas, under similar conditions access to 3-aryl and 3-alylazaphthalides is also possible. Extension of this methodology toward the preparation of 3-n-butylphthalide and chrycolide, a natural product isolated from the leaves and stems of Chrysanthemum coronarium, is also described.

  Addition of arylzincs to aldehydes was achieved by making use of the novel transmetallation of arylzincs into Cr3+ compounds. Various α-substituted benzyl alcohols or 3-substituted 1(3H)-isobenzofuranones, containing reactive functional groups, were synthesized in good yields. Me3SiCl exerted beneficial effects on the reaction.
