Minakawa, Maki;Sakurai, Yuya published 《Bismuth(III) Triflate-Catalyzed Intermolecular Cyclization of Phenols with Diols: Direct Access to O-Heterocycles》 in 2022. The article was appeared in 《Synlett》. They have made some progress in their research.SDS of cas: 599-64-4 The article mentions the following:
A direct access to O-heterocycles e.g., I by Bi(OTf)3-catalyzed intermol. cyclization of phenols such as naphthalene-2,6-diol, 2-naphthol, 4-(2-phenylpropan-2-yl)phenol, etc. with diols such as, propane-1,3-diol, pentane-2,4-diol, 2,5-dimethylhexane-2,5-diol, etc.was described. Catalytic dehydrative tandem formation of C-O and C-C bonds was achieved by using a Bi(OTf)3 catalyst without any additives. The catalytic intermol. cyclization of phenols with various diols proceeded to give the corresponding chromanes e.g., I in up to 91% yield and/or furan derivatives II [R = H, Me; R1 = iso-Pr, ethyl; R2 = H, Me; R3 = H, COOMe] up to 66% yield. The experimental procedure involved many compounds, such as 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .
4-(2-Phenylpropan-2-yl)phenol(cas:599-64-4) is a natural product found in Panax ginseng.SDS of cas: 599-64-4 4-(2-Phenylpropan-2-yl)phenol is a useful reagent for preparing and characterizing aromatic polyphosphonates as high refractive index polymers.
