[GRAPHICS]Stereoselective syntheses of (Z)-fluoroalkenoates 3a-g have been developed in three steps from the readily available fluorosulfide 5 and aldehydes, This preparation, involving a Durst reaction, was highly stereoselective and led to fluoroalkenes in 50-60% overall yields, without purification of intermediates.
