of deep-cavity cavitand 1 were functionalized by directed ortho metalation (DoM) procedures. A range of electrophilic quenchers led to hosts with ester, phenol and thioether functionality. In each case, a combination of host pre-organization and reaction control resulted in far fewer products than the theoretical sixty-nine. In addition to the nature of the lithiate, functionalization patterns were
