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 total synthesis of the potent cytotoxin theopederin D has been achieved through the use of an oxidative carbon–carbon bond cleavage reaction to form an acyliminium ion in the presence of acid labile acetal groups Other key transformations include an acid mediated functionalization of a tetrahydrofuranyl alcohol in the presence of a tetrahydropyranyl alcohol, a syn-selective glycal epoxide opening, and a catalytic asymmetric aldehyde-acid chloride condensation.

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.
