Utilization of Chloroagetone in the Synthesis of 3-Methylindoles
摘要:
Syntheses of 3-methylindoles 2 and 5 are described starting from chloroacetone and the corresponding monoalkylated anilines utilizing a modified alkylation-cyclization sequence. Compound 5 was converted in high yield into a very useful oxindole 7 in two steps.
