Abstract
Official abstract text for this publication.
Described herein are high yield methods for making magnolol analogs which are 5,5′-dialkyl-bi-phenyl-2,2′-diols.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for making 5,5′-dialkyl-biphenyl-2,2′-diols, comprising the following steps: (i) methylating biphenyl-2,2′-diol using dimethyl sulfate, to obtain 2,2′-dimethoxy-biphenyl; (ii) acylating the 2,2′-dimethoxy-biphenyl with an alkionyl chloride to obtain 2,2′-dimethoxy-5,5′-dialkionyl-biphenyl; (iii) reducing the 2,2′-dimethoxy-5,5′-dialkionyl-biphenyl to obtain 2,2′-dimethoxy-5,5′-dialkyl-biphenyl; (iv) demethylating the 2,2′-dimethoxy-5,5′-…
