Combinatorial chemistry 1, 2 and 3 is providing a new and improved approach to the discovery of new and better pharmacological agents. Small molecule libraries have been rapidly accessed using a variety of methodologies and techniques that have been developed for use in solid-phase 4 and 5 as well as solution-phase synthesis. 6 Although solid-phase synthesis has been at the forefront of combinatorial chemistry, parallel solution-phase synthesis is an interesting ...
