✦ Synopsis


Cerpegin 1 was synthesized in a one-pot reaction at room temperature catalysed by cesium carbonate with an overall of 75% yield. 3-Hydroxy-3-methyl-2-butanone 2 reacted with diethyl malonate 3 to give 2-ethoxycarbonyl-3,4,4-trimethyl-2-buten-4-olide 4. Then 4 with s-triazine gave to I,l-dimethylfuro[3,4-c]pyridine-3.4(IH, 5H)-dione 5 and which was alkylated with methyliodide to cerpegin.

A one-pot reaction sequence consisting of three consecutive metalation and electrophilic substitution stages leads to 2-(4isobutylphenyl)propanoic acid with 52% over-all yield. A crucial step is the alkylation of deprotonatedp-ethyltoluene with isopropyl bromide. In general terms, set-alkyl halides
