  摘要：

  5-Alkyl- and 5-arylalkyl-3-methylenedihydrofuran-2-ones 13a-e, 3-alkylidenedihydrofuran-2-ones 18a-c, and 3-methylenepyrrolidin-2-ones 16a-e were synthesized utilizing ethyl 2-diethoxyphosphoryl-4-nitroalkanoates 9a-e as common intermediates. All obtained compounds were tested against L-1210, HL-60, and NALM-6 leukemia cells. The highest cytotoxic activity was observed for 3-methylenefuranones 13d,e bearing benzyl or 3,4-dimethoxyphenylmethyl substituents at position 5, with IC50 values of 5.4 and 6.0 mu M, respectively. Contrary to the literature reports, no enhancement in activity due to the presence of a hydroxy group was found when the cytotoxicity of furanones 13a,b,d and 5-(1'-hydroxyalkyl)-3-methylenedihydrofuran-2-ones 6a,b,d was compared. The anticancer activity of pyrrolidinones 16a-e and 3-alkylidenefuranones 18a-c was much weaker than that of furanones 13a-e.

  Michael addition of various nitroalkanes 7a-f to ethyl (2-diethoxyphosphoryl)acrylate (6) gave 2-diethoxyphosphoryl-4-nitroalkanoates 8a-f. Transformation of the nitro functionality into hydroxy or amino group and cyclization yielded 3-(diethoxyphosphoryl)tetrahydro-2-furanones 11a-e or 3-(diethoxyphosphoryl)pyrrolidin-2-ones 14a-e, respectively. These compounds were then used in Horner-Wadsworth-Emmons olefinations of aldehydes to give 3-alkylidenedihydrofuran-2-ones 12a-e or 17a-c and 3-methylidenepyrrolidin-2-ones 15a-e.
