Hydrazines Knoevenagel condensation

Compound (248), a relative of [14] annulene containing a hydrazine bridge, has been synthesized by a Knoevenagel condensation of the [l,r-bipyrrole]-2,2 -dicarbaldehyde (247) and r-butyl cyanoacetate, followed by reduction of the exo double bond with diisobutylhaluminum hydride, acid-catalyzed cycliza-tion, and decarboxylation.283... [Pg.377]
