Abstract

Reactions of organo-metal compoundsO 0350 Facile Preparation of Various Heteroaromatic Compounds via Azatitanacyclopentadiene Intermediates. -Polysubstituted pyridines, furans, and pyrrolecarboxaldehydes are available. The reaction is highly regioselective. Starting from chiral nitriles, convenient synthesis of optically active pyridines is possible. -(SUZUKI, D.; NOBE, Y.; WATAI, Y.; TANAKA, R.; TAKAYAMA, Y.; SATO*, F.; URABE, H.; J. Am. Chem.
