Diastereoselective diels-alder reactions between substituted 1,3-butadienes and n-α-methylbenzylmaleimide
摘要:
The TiCl4 catalyzed reaction between 2-t-butyl-1,3-butadiene and N-alpha-methylbenzylmaleimide at -65-degrees-C affords diastereomeric Diels-Alder adducts in a 15:1 ratio. The structure of the major adduct was determined by x-ray.
