5-Methoxy-2-methyl-1H-indole (cas: 1076-74-0) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.HPLC of Formula: 1076-74-0

Redox-triggered dearomative [5 + 1] annulation of indoles with O-alkyl ortho-oxybenzaldehydes for the synthesis of spirochromanes was written by Cao, Lianyi;Hu, Fangzhi;Sun, Hongmei;Zhang, Xiaomei;Li, Shuai-Shuai. And the article was included in Organic Chemistry Frontiers in 2022.HPLC of Formula: 1076-74-0 This article mentions the following:

The dearomative [5 + 1] annulation of 2-methylindoles I (R = H, 4-Me, 5-F, 6-OMe, etc.) with new five-membered synthons O-alkyl ortho-oxybenzaldehydes II (R1 = t-Bu, propan-2-yl, butan-2-yl; R2 = H, Me, t-Bu; R3 = Me, ethenyl, Ph, naphthalen-2-yl, etc.; R4 = H, Me) was developed unprecedentedly through cascade [1,5]-hydride transfer/dearomative cyclization in HFIP for the synthesis of spirochromanes III bearing the 2-methylindolenine skeleton. In addition, the dual alkylation of the Me group of 2-methylindolenines was achieved by sequential operation through the redox neutral [5 + 1] annulation with the second five-membered synthon N-alkyl ortho-aminobenzaldehydes IV (R5 = Me; R6 = Et; R5R6 = -(CH2)4-; R7 = H, Cl), providing the chromane and tetrahydroquinoline fused spiroindolenines V in good yields. Furthermore, the auxiliary group that facilitates the hydride transfer process could be simply removed. In the experiment, the researchers used many compounds, for example, 5-Methoxy-2-methyl-1H-indole (cas: 1076-74-0HPLC of Formula: 1076-74-0).
