Two enantiomeric five‐membered ring building blocks from the same educt : This was achieved by reaction of 1 with two different nucleophilic reagents. 1,4‐Addition of R 2 CuLi to 1 and cleavage of MeOH furnished ( R,R )‐ 2 ; 1,2‐Addition of RM to 1 , allyl rearrangement, and MeOH‐cleavage lead to the mirror image ( S,S )‐ 2 .
