A second generation focused library of 30 tetrahydropyrimidinone amides was prepared.
The design was based on the structure of an Hsp70 modulator. This small library demonstrates
the utility of tandem multi-component reactions in structure-activity relationship
studies of biological lead molecules. The tandem Biginelli-Ugi multi-component reaction
facilitated the effective variation of four different substituents and allowed the
synthesis of the library members in a sequence of only two one-pot reactions.
