Synthesis of Aryl Ethers via a Sulfonyl Transfer Reaction
摘要:
A general synthesis of aryl ethers from primary and secondary alcohols and aryl mesylates is presented. The reaction proceeds via a sulfonyl-transfer mechanism. In this paper, we compare the sulfonyl transfer reaction to Mitsunobu ether formation. The reaction can be employed in a multistep synthesis where the aryl mesylate is used as a phenol protecting group and then as an activating group for ether formation. This protecting/activating group strategy is demonstrated using raloxifene as the target.

The present invention relates in general to the field of organic chemistry, and in particular to the preparation of benzo[b]thiophene derivatives. These benzo[b]thiophene derivatives are useful as intermediates in the synthesis of pharmaceutically active agents such as raloxifene or derivatives thereof.
