Abstract
A highly efficient and stereoselective [1,2]-phospha-Brook rearrangement of fluoromethyl ketones has been achieved by utilizing a new type of P-chiral H-phosphonate derived from CAMDOL, designated as CAMDOL-PHO. A library of 38 secondary alcohols featuring an α-trifluoromethyl or trifluoroaryl motif were afforded in up to 97% yield with 99:1 dr. Compared to other known chiral auxiliaries, bicyclic CAMDOL exhibits superior induction ability due to its unique center-chiral scaffold.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
