Favorskii-Like Rearrangement of an Aliphatic α-Halo Amide
摘要:
The reaction of the -bromoamide 2a with 1-cyclopentylpiperazine gives the Favorskii-like rearranged product 4 when the reaction is heated to 70 degrees C in a mixture of aqueous potassium hydroxide and ethanol. However, when solid sodium carbonate/potassium iodide is used in ethanol, the nonrearranged product 3a is formed instead. Supplemental materials are available for this article.

A direct transition‐metal‐free coupling between alkynes and α‐bromo carbonyl compounds has been developed with ultraviolet (UV) light in aqueous media. This method represents a facile approach to synthetically useful β,γ‐alkynyl esters and amides stereoselectively from two readily available starting materials. As an example of the synthetic application of the products, the alkynyl esters were readily

surprisingly discovered to have neuroprotectiveactivities and σ1 binding in vitro. A highly diverse set of Esaprazole analogues 2–5 was prepared in order to increase blood–brain barrier penetration. The analogues showed a structure–activity relationship at the σ1 receptor closely matching already published pharmacophores. Many of the analogues were shown to have neuroprotectiveproperties in two assays using
