The[8+4]cycloaddition of indene-2-carbaldehydes with indole-2,3-quinodimethanes and pyrrolidone-3,4-dienes is described,affording indole and pyrrolidone annulated bicyclo[4.2.1]nonanes in a highly peri-,diastereo-,and...
Herein we report the reactivity of N-(2,4-dicyano-1,5-dimethyl-3-arylcyclopenta-2,4-dienyl)-2,2,2- trifluoroacetamides and N,N-dimethyl-4-nitrosoaniline which provide compounds derived from Ehrlich-Sachs condensation,...
Sixteen new 1,6-disubstituted fulvenes have been prepared by acylation of cyclopentadienyl sodium and the result of preliminary pharmacological tests showed that several of them have antineoplastic activity.
