Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="metricconverter"> Solvent free Stobbe-condensation of methyl <img src='/image/spc_char/beta.gif'> benzoyl propionate <b>1c</b> and methyl <img src='/image/spc_char/beta.gif'>-naphthoyl propionate <b>1d</b> with benzaldehyde, anisaldehyde and furfural using dry solid potassium tertiary butoxide at room temperature and at 80°C gives <img src='/image/spc_char/beta.gif'> arylidene <img src='/image/spc_char/beta.gif'> benzoyl propionic acid <b>2a-c</b> and <img src='/image/spc_char/beta.gif'> arylidene <img src='/image/spc_char/beta.gif'> naphthoyl propionic acid <b>2d-f</b> respectively. Base-catalysed solvent free Stobbe condensation of dimethyl succinate <b>1e</b> and aliphatic and aromatic ketones at room temperature gives 1,1-alkylidene monomethyl succinate <b>3a,b</b> and 1,1-arylidene monomethyl succinate <b>3c</b> respectively. </smarttagtype>
