A Modular Rearrangement Approach toward Medicinally Relevant Phosphinic Structures
摘要:
An unprecedented coupling of a P-C and a C-C bond-forming event in a practical operation was developed to access medicinally relevant phosphinic structures. The strategy relies on an Ireland-Claisen rearrangement triggered by the phospha-Michael addition of silyl phosphonites to allyl acrylates. This protocol was extended to a more versatile three-component variant that utilizes phosphinic acids, acryloyl chlorides, and allylic alcohols as starting materials.
