used to form macrocycles by 'dimerization' through ring-closingmetathesis. Hereby the introduction of templates connecting the two building blocks favors the dimerization over oligomerization or polymerization reactions. Attachment of the template through imine formation allows the removal of the template simultaneous to the reduction of the double bonds formed during ring-closingmetathesis. Unsymmetric
