antiviral potency or increased cytotoxicity to MT-4 cells. Finally, we synthesized a series of analogues in which the ring size of the bis-pyridyl macrocycles was varied between 12 and 16 members per ring including the py[iso-14]aneN(4) ring system, an isomer of the py[14]aneN(4) macrocycle. The p-phenylenebis(methylene)-linked dimer of the py[iso-14]aneN(4) (AMD3329) displayed the highest antiviral activity
Abstract A facile two-step synthesis of methylketones from alkyl nitriles via the Blaise conversion of nitriles into β-keto esters and acid-mediated hydrolysis followed by decarboxylation of the resulting β-keto esters is described.

Synthesis of 1,11-dithia-4,8-diazacyclotetradecane (L1), a constitutional isomer of the macrocyclic [14]aneN2S2 series, is accompanied with reaction and method optimization. Chelation of L1 with copper(II) provided assessment of lattice packing, ring contortion, and evidence of conformational fluxionality in solution through two unique crystalstructures: L1Cu(ClO4)2 and [(L1Cu)2μ-Cl](ClO4)3.
