of diverse macrocycles with different ring sizes from two easily accessible building blocks is presented. Reacting diolprecursors with electrophilic reagents lead to 17-membered sulfites and 19-membered malonates in 34–79% yield. Double-reductive amination of dialdehyde analogs of the diolprecursors leads to 15-membered amines in yields ranging from 9 to 60%, reflecting large differences in reactivity

class of lead compounds. The low abundance of these molecules can, in part, be explained by the inherent difficulties in the synthesis of macrocycles and the lack of general methods for their rapid assembly. We have undertaken a research program aimed at developing methods for facile synthesis of macrocycles from simple precursors. The synthesis of two new cyclization precursors is described and the
