Description / Table of Contents:
New Heterocyclic Compounds from N-(2-Thienyl)chloroformamidines and N-NucleophilesN-(2-Thienyl)chloroformamidines 1a - c form unstable intermediates with nucleophilic reagents. These cyclize by two different mechanisms to give thieno[2,3-d]pyrimidines 2-5. Reactivities and mechanisms are discussed.
Notes:
N-(2-Thienyl)chlorformamidine 1a - c bilden mit geeigneten nucleophilen Reagenzien instabile Zwischenstufen, die nach zwei verschiedenen Mechanismen zu Thieno[2,3-d]pyrimidinen 2-5 cyclisieren. Reaktivitäten und Bildungsmechanismen werden diskutiert.
