| Abstract: | Solvent free Stobbe-condensation of methyl  benzoyl propionate 1c and methyl -naphthoyl propionate 1d with benzaldehyde, anisaldehyde and furfural using dry solid potassium tertiary butoxide at room temperature and at 80°C gives arylidene benzoyl propionic acid 2a-c and arylidene naphthoyl propionic acid 2d-f respectively. Base-catalysed solvent free Stobbe condensation of dimethyl succinate 1e and aliphatic and aromatic ketones at room temperature gives 1,1-alkylidene monomethyl succinate 3a,b and 1,1-arylidene monomethyl succinate 3c respectively. |
