Conversion of substituted benzyl ethers to diarylmethanes. A direct synthesis of diarylbenzofurans
摘要:
The Lewis acid catalyzed rearrangement of substituted benzyl ethers affords diarylmethanes in good yields. One of the products was converted into a diarylbenzofuran using a benzoylation/P4-tBu cyclization protocol. (C) 2012 Elsevier Ltd. All rights reserved.
