Convergent Synthesis of (R)-Silodosin via Decarboxylative Cross-Coupling.

ABSTRACT: A new approach to Silodosin capitalizing on a radical retrosynthetic strategy to dissect the molecule into two halves is reported. Using a reductive decarboxylative cross-coupling, a simple indoline can be coupled to a chiral pool-derived fragment to arrive at the target in only seven steps (LLS). This route avoids the use of resolution strategies or asymmetric hydrogenation that requires a subsequent Curtius rearrangement to install a key amino functionality.
