Synthesis and Facile Ring Opening of 2,3,4-Triphenyl-3-azabicyclo[3.2.0]hepta-1,4-diene
摘要:
The first synthesis of 2,3,4-triphenyl-3-azabicyclo[3.2.]-hepta-1,4-diene (pyrrolocyclobutene) that has no substituent in the cyclobutene moiety, Is described. This compound underwent an extremely facile electrophilic attack at the beta position to give the ring opened product.
