LOW-VALENT TITANIUM INDUCED REDUCTIVE CYCLIZATION OF 4,4-DICYANO-1,3-DIARYL-1-BUTANONE - APPLICATION TO THE SYNTHESIS OF 1-AMINO-2-CYANOCYCLOPENTENE DERIVATIVES

摘要

Titanium tetrachloride was reduced by zinc powder in THF to produce low-valent titanium which reacted with 4,4-dicyano-1,3-diaryl-1-buanone to give the derivatives of 1-amino-2-cyanocyclopentene. [References: 4]
