Diastereoselective conjugate additions of ethoxyvinyllithium to aromatic and α,β-unsaturated oxazolines
摘要:
Ethoxyvinyllithium (EVL) adds cleanly to unsaturated oxazolines, which upon hydrolytic work-up afford the corresponding ketones in high yields and excellent diastereoselectivity. (C) 1998 Elsevier Science Ltd. All rights reserved.

2-(1-phenyl-1,2,3,4-tetrahydronaphthalen-1-yl)-2-oxazoline, respectively. The major products from the precursor with a 5-C-atom spacer were derivatives of benzocycloheptane in which the oxazoline group had undergone a novel areneotropic migrationfrom the end of the spacer to the benzo ring. The product from reaction of the corresponding 2-C-atom precursor was a 9-oxazolinophenanthrene derivative. EPR
