Ni-Catalyzed Suzuki-Miyaura Cross-Coupling of alpha-Oxo-vinylsulfones to Prepare C-Aryl Glycals and Acyclic Vinyl Ethers

We demonstrate that readily available and bench-stable alpha-oxo-vinylsulfones are competent electrophiles in Ni-catalyzed Suzuki-Miyaura cross-coupling reactions. The C-sulfone bond in the alpha-oxo-vinylsulfone motif is cleaved chemoselectively in these reactions, furnishing C-aryl glycals or acyclic vinyl ethers in high yields. These reactions proceed under mild conditions and tolerate a remarkable scope of heterocycles and functional groups. Preliminary mechanistic studies revealed the importance of an alpha-heteroatom in facilitating these transformations.

A concise and practical stereoselective synthesis of ipragliflozin L-proline

A concise and practical stereoselective synthesis of ipragliflozin L-proline was presented starting from 2-[(5-iodo-2-fluorophenyl)methyl]-1-benzothiophene and 2,3,4,6-tetra-O-pivaloyl-alpha-D-glucopyranosyl bromide without catalyst via iodine?lithium?zinc exchange.

Discovery of Ipragliflozin (ASP1941): A novel C-glucoside with benzothiophene structure as a potent and selective sodium glucose co-transporter 2 (SGLT2) inhibitor for the treatment of type 2 diabetes mellitus

A series of C-glucosides with various heteroaromatics has been synthesized and its inhibitory activity toward SGLTs was evaluated. Upon screening several compounds, the benzothiophene derivative (14a) was found to have potent inhibitory activity against SGLT2 and good selectivity versus SGLT1. Through further optimization of 14a, a novel benzothiophene derivative (14h; ipragliflozin, ASP1941) was discovered as a highly potent and selective SGLT2 inhibitor that reduced blood glucose levels in a dose-dependent manner in diabetic models KK-Ay mice and STZ rats.

Synthesis of aryl ethers via a sulfonyl transfer reaction

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.
