| Abstract: | A series of 2,4-disubstituted butanolides was prepared based on the trans-stereoselective electrophilic cyclization of substituted N-(pent-4-enoyl)pyrrolidines. The butanolides may be considered as synthons for this type of natural products. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 1, pp. 124–129, January, 2007. |
