An improved synthesis of 3-methyl-5-hydroxy protected indoles
Marino,Hurt
, p. 839 - 848 (2007/10/02)
The synthesis of 3-methyl-5-alkoxy indoles 14 and 15 was accomplished through the use of DIBALH to effect the reductive- cyclization of an amino-nitrile intermediate. The mild conditions used to induce cyclization allowed for the use of a benzyl protectin
