“…The diverse array of natural 2,3′-bis(indolyl)methane (2,3′-BIM) alkaloids offers access to new and exciting chemical scaffolds, demonstrating the potential for the development of drugs possessing significant anticancer and anticholinesterase activities. 1 , 2 Among the various 2,3′-BIM skeletons, derivatives of 3-(indol-2-yl)-3-(indol-3-yl)-1,2-propanediol (IIPDO) containing two chiral carbons emerge as particularly appealing entities ( Figure 1 ).…”

The short and first total synthesis of (+)-colletotryptins B-D, ent-colletotryptin A, and diastereomer of mucronatin B, which are a group of natural 3-(indol-2-yl)-3-(indol-3-yl)-1,2-propanediol (IIPDO) analogues containing two stereogenic centers at the C8′ and C9′ positions, isolated from endophytic fungus Colletotrichum sp. SC1355 and Tetrapterys mucronata, respectively, has been successfully accomplished in two and three steps with overall yields ranging from 28 to 54%. Key features of this synthesis include an innovative Bi(OTf) 3 -catalyzed stereoselective transindolylation of (S)-3,3′-di(1H-indol-3-yl)propane-1,2-diol. The operational simplicity, environmentally friendly catalyst, and broad functional group tolerance of this modular strategy render it suitable for adoption in both academic and industrial settings.

“…In addition, O -heterocycle 10 was obtained in 92% yield on conversion of the benzaldehyde motif in 2a to the benzonitrile group with Ph 2 P(O)ONH 2 in toluene at 80 °C for 4 h (Scheme g) . In a final experiment, InBr 3 -catalyzed Friedel–Crafts arylation of 2a with 1 H -indole in 1,2-dichloroethane at room temperature for 12 h was demonstrated to afford the bis(indolyl)methane-substituted furan 11 in 90% yield (Scheme h) …”
