Improved procedures have been developed for the synthesis of P1aspartate-based 2,6-dichlorobenzoyloxymethyl ketone 1 and fluoromethylketone 2, the prodrugs of two potent ICE-inhibitors. 1 was prepared from (R)-trans-4,5-O-isopropylidene-4,5-dihydroxy-2-pentenecarboxylic acid ethyl ester; 2 was obtained via a nitro-aldol condensation as key step from in situ generated fluoroacetaldehyde.

As a continuation of our SAR studies of dipeptidyl aspartyl-fmk as caspase inhibitors, we explored the replacement of the P(2) aminoacid by a 2-aminoaryl acid or other non-natural aminoacids. Several of these compounds, such as 6l and 6p, were found to have good activities with inhibition potencies of around 100 nM in a caspase-3 enzyme assay. EP1113, Z-Val-(2-aminobenzoyl)-Asp-fmk (9b), is identified

The addition of nitrile oxides to [60]fullerene is examined and it is
found that the reaction products regenerate [60]fullerene under relatively
mild conditions; the result is potentially useful for better control of
fullerene functionalization.
