Cyclohexenylboration of Aldehydes and Ketones with the Borabicyclo[3.3.2]decanes (BBDs)

18-Aug-2015 | Eduvigis González; Lorell Muñoz-Hernández; Eyleen Alicea; Bakthan Singaram; George W. Kabalka; John A. Soderquist, Organic Letters, 2015

Asymmetric hydroboration of 1,3-cyclohexadiene with 4R produces the allylborane 5RR as essentially a single diastereomer (i.e., no observable 5RS), and its addition to representative aldehydes provides 9RS (52–75%) with excellent selectivity (94–99% ee). By contrast, a similar sequence with the ...

Unusual Intramolecular Hydrogen Transfer in 3,5-Di(triphenylethylenyl) BODIPY Synthesis and 1,2-Migratory Shift in Subsequent Scholl Type Reaction

17-Aug-2015 | Ming Hui Chua; Kuo-Wei Huang; Jianwei Xu; Jishan Wu, Organic Letters, 2015

The straightforward synthesis of 3,5-di(triphenylethylenyl) BODIPYs 1–3 from the condensation of 2-(triphenylethylenyl) pyrrole with aryl aldehydes are surprisingly found to produce side products that are hydrogenated at one of the two triphenylethylene substituents. It was also observed that the ...

Synthesis of Fluoroalkoxy Substituted Arylboronic Esters by Iridium-Catalyzed Aromatic C–H Borylation

17-Aug-2015 | Farhat Batool; Shehla Parveen; Abdul-Hamid Emwas; Salim Sioud; Xin Gao; Munawar A. Munawar; Ghayoor A. Chotana, Organic Letters, 2015

The preparation of fluoroalkoxy arylboronic esters by iridium-catalyzed aromatic C–H borylation is described. The fluoroalkoxy groups employed include trifluoromethoxy, difluoromethoxy, 1,1,2,2-tetrafluoroethoxy, and 2,2-difluoro-1,3-benzodioxole. The borylation reactions were carried out neat ...
