Abstract
High Resolution Image Download MS PowerPoint Slide A general strategy for the synthesis of 2 N,4 N ′-disubstituted glycoluril enantiomers on a multigram scale using orthogonal protection is reported. The use of these glycolurils is demonstrated in the synthesis of enantiomerically pure bambus[6]uril macrocycles. Moreover, the deprotection of ( S )-1-phenylethyl substituents on the macrocycle was achieved, opening access to various chiral bambus[6]urils via post-macrocyclization modification strategy.
