Abstract
We present here a versatile and efficient Ni-H-catalyzed hydroalkylation reaction of terminal alkynes and α-bromo phosphonates with Markovnikov selectivity, yielding a range of allylic phosphate terminal alkenes. This reaction demonstrates a broad substrate scope and excellent functional group compatibility, including those with complex structural motifs found in natural products and pharmaceuticals. The practical applicability is demonstrated through gram-scale reactions and product transformations. In addition, the methodology is also applicable to the substrates of benzyl bromides and bromo amides.
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.
