Tholander, Joakim,Bergman, Jan
, p. 1619 - 1622 (1998)
Dichloroacetylation of 2,3-diindolylmethane followed by a tandem cyclization-hydrolysis reaction under acidic conditions gave the title compound.
Enhancement of chemically-induced HL-60 cell differentiation by 3,3′-diindolylmethane derivatives
Noguchi-Yachide, Tomomi,Tetsuhashi, Masashi,Aoyama, Hiroshi,Hashimoto, Yuichi
, p. 536 - 540 (2009)
3,3′-Diindolylmethane (DIM, 1) and its derivatives have been prepared, and their enhancing effects on chemically-induced HL-60 cell differentiation were analyzed. Among the prepared compounds, IndDIM (12) showed the most potent enhancing effect on HL-60 cell differentiation induced by chemicals, including retinoids, 1,25-dihydroxyvitamin D3, 12-O-tetradecanoyl phorbol-13-acetate and dimethyl sulfoxide.
Protocols for the Syntheses of 2,2′-Bis(indolyl)arylmethanes, 2-Benzylated Indoles, and 5,7-Dihydroindolo[2,3- b]carbazoles
Lafzi, Ferruh,Kilic, Haydar,Saracoglu, Nurullah
, p. 12120 - 12130 (2019/10/11)
The electrophilic substitution reaction of 4,7-dihydroindole with aryl-aldehydes as an electrophilic partner followed by an oxidation step to deliver 2,2′-bis(indolyl)arylmethanes was studied for the first time. The reaction afforded regioselectivity at the 2,2′-positions of indole in an operationally simple and inexpensive procedure with a variety of substrates. To the best of our knowledge, this is the first set of examples of 2,2′-bis(indolyl)arylmethanes obtained in a substituent-free manner. A facile method from dipyrromethanes to the corresponding 2-benzylindoles was also reported. In addition, 2,2′-bis(indolyl)arylmethanes were converted to 5,7-dihydroindolo[2,3-b]carbazoles.
