DIAS, Luiz C.; SHIMOKOMAKI, Simone B.  and  SHIOTA, Robson T.. Short Synthesis of a New Cyclopentene-1,3-dione Derivative Isolated from Piper carniconnectivum. J. Mex. Chem. Soc [online]. 2005, vol.49, n.2, pp.244-251. ISSN 1870-249X.

The total synthesis of cyclopentene-1,3-dione (1), a new natural cyclopentenedione derivative isolated from the roots of Piper carniconnectivum, is described in 8 steps and 11% overall yield from 2-acetylfuran, giving a 57:43 mixture of the two possible geometric isomers 1a and 1b.

Keywords : aldol reaction; allylic alcohol oxidation; cyclopentenedione derivative; Piper carniconnectivum.
