Mono- and Dihydroxylated Symmetrical Octamethylcucurbiturils and Allylated Derivatives

Mono- and dihydroxylated symmetrical octamethylcucurbit[6]urils {(OH)OMeQ[6] and (OH)2OMeQ[6]} were prepared using a photochemical method to introduce limited alcohol group(s) directly to the parent symmetrical octamethylcucurbit[6]uril (OMeQ[6]), and the resulting compounds were verified by 1H NMR, Xevo Q-TOF MS, and X-ray crystallography. Further chemical modification of mono- and dihydroxylated OMeQ[6] was also performed.
