520 $a The synthesis of a 10,000-member library of molecules bearing the tetracyclic carpanone core is described in this thesis. The synthesis of the carpanone core was inspired by the proposed biosynthesis of the natural product. A PhI(OAc)2 mediated oxidative phenolic coupling reaction was developed to construct a carpanone-like structure. In addition to coupling two identical phenols, this reaction also allows the coupling of two different phenols. A single product was obtained in cases involving two different phenols by manipulating the electronic properties of the coupling partners.*
520 $a Various diversity-generating reactions were used during library thesis. A tandem oxime formation amine 1,4-addition reaction was developed to incorporate an oxime and a secondary amine into the carpanone core. The secondary amines were then converted to a variety of amides, carbamates, ureas and sulfonamides. In a different route, the core was subjected to a thio 1,4-addition reaction followed by oxime formation to incorporate a different set of building blocks. Furthermore a tandem oxime formation azide 1,4-addition was performed on the core. The azide introduced was then converted to triazoles via a cycloaddition reaction with alkynes. Finally, the phenols generated after deallylation of the core were subjected to Mitsunobu reaction, biaryl coupling and carbamate formation to give about 10,000 structurally complex molecules containing a diverse collection of functional groups.
