Failure-mode index

Search what already failed

A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.

WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Ugi multicomponent reactions of optically active aldehydes and chiral aminoindanols: diastereoselective synthesis of bisamides relevant to SARS-CoV-2 Mpro inhibitors.

Ghosh AK, Bhattacharjee A, Jayashankar U et al. · 2026 · Organic & biomolecular chemistry

We have investigated diastereoselective Ugi-multicomponent reactions (Ugi-MCR) relevant to bis-amide scaffolds related to SARS-CoV-2 main protease (Mpro) inhibitors. The studies were mainly focussed on development of diastereoselective…
