DOI: 10.1039/c7cc04339b
Abstract: A palladium-catalyzed aminocarbonylation of halo-substituted 7-azaindoles utilizing CHCl3 as the carbonyl source has been developed for the straightforward incorporation of an amide functional group. The protocol was extended to other heteroarenes such as pyrazolopyridines and… read more here.

DOI: 10.3390/md20070438
Abstract: The enantiomers of 6-fluoro-, 6-bromo-, and 6-iodopericosine A were synthesized. An efficient synthesis of both enantiomers of pericoxide via 6-bromopericosine A was also developed. These 6-halo-substituted pericosine A derivatives were evaluated in terms of their… read more here.
