## Abstract Among the reactions available to synthetic chemists for the construction of new CC bonds, the Claisen rearrangement is one of the most powerful, elegant, and well‐characterized methods. A genuinely new variant, the Belluš–Claisen rearrangement came to light a quarter of a century ago:
## Abstract The __Claisen__ rearrangement of the __N__‐protected, silylated allyl glycinates **11** and **12** led to the formation of allyl/silyl‐functionalized amino acids **13** and **14** in yields up to 80%. The diastereoisomer ratio varied from 2 : 1 to 29 : 1 for **11mb**, and from 2 : 1 to
## Abstract During the reaction of allyl ethers, allyl sulfides and allyl selenides with __in situ__ prepared dichloroketene (**1**), 2 competing pathways are observed. Besides [2+2]‐cycloaddition, an unprecedented [3,3]‐sigmatropic (__Claisen__) rearrangement via a 1,3‐dipolar intermediate takes p
