A modular strategy for the synthesis of a variety of axiallychiraldicarboxylicacids bearing 3,3′‐disilyl groups has been developed. Dehydrogenative silalactonization and subsequent Grignard addition offered a straightforward way towards axiallychiral3,3′‐disilyl dicarboxylicacids in good yields (see scheme; LiTMP=lithium 2,2,6,6‐tetramethylpiperidide).
