Synthesis of some mellein derivatives

, p. 116 - 117 (2007/10/02)
Synthesis of some mellein derivatives (IIIa-d) have been carried out using o-lithiation reaction. o-Lithiation of substituted N-methylbenzamides (Ia-d) and with n-BuLi followed by alkylation with propylene oxide gives 3-methyl-3,4-dihydroisocoumarins (IIa-c) and 5,6-dimethoxymellein (IIId). (IIa-c) have been converted to IIIa-c by HBr/AcOH or anhyd.AlCl3.
A NEW PATHWAY TO 1,3,4(2H)-ISOQUINOLINETRIONES AND SUBSTITUTED ISOINDOLINONES
Vekemans, Jozef,Hoornaert, Georges
, p. 943 - 950 (2007/10/02)
A new synthesis in the isoquinoline series is discussed: the reaction of appropriate benzamides and oxalyl chloride affords isoquinolinetrions along N-aroyloxamoyl chlorides.The solvent effect, the acid catalysis and the isomer distribution are accounted
