The invention relates to processes and compounds useful for producing modified aspartic acid derivatives, such as aspartic acid aldehyde moieties. Aspartic acid derivatives are useful for preparing caspase inhibitors and / or prodrugs thereof.

Disclosed herein is a method for making compounds that are useful as caspase inhibitor prodrugs of formula I: wherein R1 is an optionally substituted group selected from an aliphatic group, aralkyl group, heterocyclylalkyl group or aryl group, and R2 is preferably a P2—P4 moiety of a caspase inhibitor. Key intermediates include the azidolactones III and VIII:

This invention provides compounds of formula I:wherein Z is oxygen or sulfur; R1 is hydrogen, —CHN2, R, CH2OR, CH2SR, or —CH2Y; next to R3 represents a single or double bond; Y is an electronegative leaving group; R2 is CO2H, CH2CO2H, or esters, amides or isosteres thereof; R3 is a group capable of fitting into the S2 subsite of a caspase enzyme; R4 is a hydrogen or C1-6 alkyl or R3 and R4 taken together form a ring; Ring A and Ring B are each heterocyclic rings, and R and R5 are as described in the specification. The compounds are effective inhibitors of apoptosis and IL-1β secretion.
