The utility of covalently bonded metalloid templates is demonstrated by syntheses with (a) Bu 2 SnO and (b) Me 2 Si(NCO) (or Me 2 Si(NCS) 2 ). Approach (a) leads to macrocycles from diols and diisocyanates, and approach (b) gives unsymmetrically substituted heterocycles from symmetrical reactants (Im imidazolyl).
