    The chiral allene formation reactions catalyzed by palladium occur via a syn elimination mechanism, but there is a lack in understanding of the stereoselectivity in rhodium catalyzed reactions, specifically the β-OH elimination step. Here, the authors report the sterically controlled Rh-catalyzed SN2’-type substitution reactions of tertiary propargylic alcohols with arylmetallic species affording the non-readily available enantioenriched tetrasubstituted allenes via either exclusive syn- or anti-β-OH elimination.

Here, the authors achieve this by optical resolution of the corresponding racemic (quasi-)static α-helical peptide with double stapling, which effectively freezes the interconversion between the right-handed (P)- and left-handed (M)-α-helices.
