α,β-unsaturated oxazolines, a powerful tool in asymmetric diels-alder cycloadditions

α,β-Unsaturated oxazolines 10, 12, and 16, activated with trifluoroacetic anhydride, proved to be very powerful dienophiles toward various dienes such as 17-23 including Danishefsky type diene. The reactions were performed generally between -100 and -20 °C and the diastereoselectivity is usually better than 90%.

CHIRAL α,β-UNSATURATED OXAZOLINES IN THE ASYMMETRIC DIELS-ALDER REACTION

α,β-Unsaturated oxazolines derived from (+)-camphor become powerful dienophiles in asymmetric Diels-Alder reaction after activation with trifluoroacetic anhydride.
