  The Synthesis of Mycophenolic Acid from 2,4-Dihydroxybenzoic Acid

  摘要：

  Mycophenolic acid (1) has been synthesized from 2,4-dihydroxybenzoic acid by regioselective introduction of the three required carbon substituents. A key transformation in this sequence is the introduction of the methyl substituent at position 5 by a rapid, uncatalyzed replacement of the bromide in 8 at low temperature by methyllithium. The scope and mechanism of this methylation reaction are examined.
