名称:
Captodative α,β-unsaturated oxazolines as dienophiles in the asymmetric Diels-Alder reaction
摘要:
Captodative oxazoline derivative 5a gave rise to four-cycloadducts 6,7,8 and 9 in the presence of trifluoroacetic anhydride and cyclopentadiene. Hydrolysis of 6 led to alpha-phenylthio carboxylic acid 14.
