Evolution of Dithiane-Based Strategies for the Construction of Architecturally Complex Natural Products

Abstract: Umpolung-based strategies play a significant role in organic synthesis. Particularly important are 1,3-dithiane linchpins, which serve as convenient acyl anion equivalents. The general synthetic accessibility and impressive reactivity of 1,3-dithianes have thus led to widespread application. Since the late 1970s, dithianes have featured prominently in our program directed toward the synthesis of complex natural and unnatural products, both for effective union of advanced fragments and for multicomponent linchp… Show more

“…[4] A modern concept utilizes the umpolung of aldehydes, for example, by application of the Stetter reagent [5] or 1,3-dithiane derivatives. [6] Recently, we reported the cerium-catalyzed a hydroxylation of 1,3-dicarbonyl compounds 1 (Scheme 1). [7] With respect to economical and ecological considerations, the use of molecular oxygen is superior to other reagents applied in this type of conversion.…”

“…[1] This strategy permits the rapid and efficient assembly of molecular complexity in a "single flask" with precise stereocontrol. The ARC tactic can be broadly divided into two classes based on the mode of negative charge migration, that occurs either "through-bond" or "through-space" (Figure 1).…”
