Abstract

Tetraarylcyclopentadienones 2a–c react with (E)‐3,4,5,6,7‐penta‐O‐acetyl‐1,2‐dideoxy‐1‐C‐nitro‐D‐galacto‐ (1a) and ‐D‐manno‐hept‐1‐enitol (1b) to give 1‐C‐(2,3,4,5‐tetraarylphenyl)‐D‐galacto‐ (3a–c) and ‐D‐manno‐penta‐O‐acetylpentitol (3d‐f), respectively, after decarbonylation and HNO~2~ elimination from the Diels‐Alder cycloaddition intermediates.

## Abstract The condensation of 1 or 3 [^14^C] n‐butylmalonate diethyl ester (III) with hydrazobenzene (IV) yields up to 90 per cent of 3 or 5 [^14^C] 4‐butyl‐1, 2‐diphenyl‐3, 5‐pyrazolidinedione, if n‐butyl alcohol is used as a solvent and the corresponding sodium alcoholate as a condensing agent
