Xia, Ai-Bao; Pan, Gong-Jian; Wu, Chao; Liu, Xue-Li; Zhang, Xiao-Long; Li, Zhao-Bo; Du, Xiao-Hua; Xu, Dan-Qian published the artcile< Enantioselective One-Pot Reaction: Organocatalyzed Synthesis of Fully Functionalized Oxabicyclo[2.2.2]octanes with Seven Contiguous Stereocenters>, Product Details of C9H7BrO, the main research area is stereoselective preparation oxabicyclooctane seven contiguous stereocenter; organocatalytic stereoselective Michael Henry hemiacetalization unsaturated aldehyde ketoamide nitroalkene.
An enantioselective one-pot Michael/ Michael/ Henry/ hemiacetalization reaction between α,β-unsaturated aldehydes, α-ketoamides, and nitroalkenes under mild conditions catalyzed by a diarylprolinol silyl ether has been developed. The sequential methodol. provides a direct approach to a wide range of fully substituted chiral oxabicyclo[2.2.2]octanes with seven contiguous stereocenters in moderate to excellent yields (up to 99%), high to excellent diastereoselectivities (up to >25:1 dr), and high to excellent enantioselectivities (up to 99% ee).
Advanced Synthesis & Catalysis published new progress about Acetalization. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Product Details of C9H7BrO.
