    Notes: Synthesis of New N, N,1,1-Tetramethyl-isobenzofuranaminesThe nitrophthalides 3a-d aimed as intermediates in the synthesis of the title compounds 6a-d were obtained via regioselective reduction of 3-nitrophthalic anhydride 1 or by nitration of phthalide and 3,3-dimethylphthalide, respectively. Reductive methylation of the nitro groups afforded the dimethylaminophthalides 5a-d which in turn were reacted with MeMgI or in the case of 5d reduced by LiAlH4 leading finally to the title compounds.

    Synthesis of Isobenzofuran Derivatives as heterocyclic analogues of the herbicide sindone B (1994)

    Notes: The target compounds 21-27 were synthesized via bromination of the N,N,1,1-tetramethylisobenzofuranamines 13, 15 and 16, subsequent bromine-lithium exchange and reaction with propanal or propanoyl chloride, respectively. In the course of some model reactions undertaken to test a synthetic strategy based on directed ortho-lithiation governed by the dimethylamino-group a useful synthesis of the ketone 3 was developed.
