Two routes compete in the alkaline hydrolysis of phenyl-9-m-carboranylbromonium borofluoride: nucleophilic substitution with cleavage in the main Br-B bond, giving bis(9-m-carboranyl) ether as the main product, and one-electron reduction with predominant cleavage of the Br-C bond....

(Spengler, 1997). This compound was used successfully during seven successive cycles of manual cleavage coupled with MS analysis. Nevertheless, the high reactivity of such compounds seems to shows artefactual modification such as“acetylation' of the hydroxyl groups of the Ser and Thr. Allyl ...
Production of the free phenol by ether cleavage1-(4,hydroxyphenyl-2-methyl-2-morpholinopropanone-1131.7 g (0.5 mol) of 1-(4-methoxyphenyl)-2-methyl-2-morpholinopropanone-1 are dissolved in 300 ml of hydrobromic acid (about 47%), and the solution is stirred at 120° C. for 24 hours. ...
Cleavage of the methyl ether in 31 with BBr3 produced phenol 10, which was the intermediate in the racemic synthesis. We are now working on the further transformation toward the asymmetric total synthesis. 展开 DOI: 10.24496/tennenyuki.57.0_Oral3 年份: 2015 ...
Most of the racemization occurs in the cyclization/cleavage step. Although optimization of partial racemization using a mixture of TFA and boron trifluoride (BF3)-ethyl ether complex, which is effective in suppressing racemization in the cyclization/cleavage reaction. The partial racemization in PTH ...
