The intermolecular and intramolecular reductive coupling reactions of arylmethylidenemalononitriles induced by SmI2 have been studied. The configuration of the cyclodimerization products, 4,5-trans-isomers of 2-amino-1,3,3-tricyano-4,5-diarylcyclopentenes, has been confirmed by X-ray analysis and a possible reaction mechanism is proposed.

A highly diastereo- and enantioselective phosphine-catalyzed sequential [3 + 2]/[3 + 2] annulation of allenoates with arylidenemalononitriles has been developed. This reaction allows for the facile construction of multifunctionalized cis-fused bicyclic[3,3,0]octene scaffolds, encompassing three consecutive stereogenic centers with one quaternary carbon center, in a one-step operation from readily available

There are provided pharmaceutical compositions containing as an active ingredient a compound of the general formula (I):
wherein R₁ and R₂ are each independently CN, CONH₂ or COOH or one of R₁ and R₂ may be -CSNH₂ or, when R₁ is CN, R₂ can also be the group
R₃ is H, CH₃ or OH,
R₄, R₅, R₆, R₇ are each independently H, OH, C₁₋₅ alkyl, C₁₋₅ alkoxy. NH₂, CHO, halogen, NO₂ or COOH, or R₄ and R₅ together may represent a group -O-CH₂-O-;
provided that: (a) when R₄ and R₇ are each OH, R₃, R₅ and R₆ are each H and one of R₁ and R₂ is CN, then the other of R₁ and R₂ cannot be CONH₂; and (b) when R₃ and R₇ are each H, R₅ is OH and R₄ and R₆ are both H or both C₁₋₅ alkyl, then R₁ is CN and R₂ is CN or the group
or a pharmaceutically acceptable salt thereof.
There are also provided some novel compounds of formula (I) above.
The compositions and compounds according to the invention are efficient protein-tyrosine kinase inhibitors and are suitable for the inhibition of proliferative processes in mammalian cells.
