Compounds that include a pederin, psymberin or pederin/psymberin chimera scaffold. The pederin scaffold includes a substituent at the C10 and/or C13 position that may include a linker that may be conjugated to a targeting moiety. The psymberin scaffold includes a substituent at the C8 and/or C11 positions that may include a linker that may be conjugated to a targeting moiety. The pederin/psymberin chimera scaffold includes a substituent at the C10 and/or C13 position that may include a linker that may be conjugated to a targeting moiety. The pederin, psymberin or pederin/psymberin chimera scaffold may be modified to include substituents at positions other than the C10 or C 13 of pederin, or the C8 and C11 of psymberin.

The N-7-C-25 fragment of the potent and selective cytotoxic agent psymberin has been prepared through a short (12 linear steps, 15 total steps) and stereoselective sequence. Highlights of this route include a very rapid construction of the pentasubstituted arene, a substrate-controlled diastereoselective fragment coupling using a Mukaiyama aldol reaction, and an efficient entry into a key tetrahydropyranyl cyanide.
