The present invention relates to methods of preparing fused ring indeno compounds that involves reacting together a dienophile and a lactone compound, in the presence of a catalyst, and a carboxylic acid anhydride. With some embodiments, the fused ring indeno compound is represented by the following Formula (I-A), the dienophile is represented by the following Formula (II-A), and the lactone compound is represented by the following Formula (III-A):
The atom-efficientcross-couplingreaction of triarylbismuths with a variety of aliphatic, aromatic, and hetero-aromatic acylchlorides was demonstrated to afford high yields of cross-coupled ketones under palladium catalysis. The corresponding cross-couplingreaction with diacid chlorides also furnished bis-coupled ketones in good yields.
The one-pot, cross McMurry coupling between two different diaryl ketones gave structurally varied tetraarylethenes in 59-80% isolated yields. This synthetic protocol is more convenient and effective compared to previously reported procedures

An optimized procedure for the direct and regioselective arylation of 2-acylfurans has been developed. The versatility of this protocol has been evaluated on a series of aryl and heteroaryl halides, thus obtaining a small collection of 2,5-disubstituted furans in moderate to good yields. Finally, the optimized protocol has been successfully applied to the synthesis of the HIV-1 integrase inhibitor 3 and could be further exploited for the generation of novel substituted furans as potential integrase inhibitors.
