Stereoselective synthesis of Z-3-alkoxy-2-[(4′-methoxyphenyl)methylidene]-1(3H)-isobenzofuranones
摘要:
Photoreorganisation of 2-alkoxy-2-(4'-methoxyphenyl)-1H-indene-1,3(2H)-diones in anhydrous acetone affords exclusively Z-3-alkoxy-3-[(4'-methoxyphenyl)methylidene]-1(3H)-isobenzofuranones. The products were identified by X-ray crystallography of one of them. (C) 2003 Elsevier Science Ltd. All rights reserved.
