摘要：

Several cases of significant enhancement in the diastereoselectivity of acyclic Claisen rearrangement of cyclohexenyl allyl ethers governed principally by remote asymmetric center(s) have been observed when Lewis acid catalysts are employed rather than the usual thermal rearrangement conditions.
