A palladium-catalyzed C-H functionalization/intramolecular asymmetric allylation cascade of N-sulfonyl benzamides with 1,3-dienes has been developed. In the presence of a chiral pyridine-oxazoline ligand, this protocol enables the synthesis of chiral 3,4-dihydroisoquinolones in yields of up to 83% with enantioselectivities of up to 96%, using environmentally friendly air as the terminal oxidant.
已经开发了钯催化的N-磺酰基苯甲酰胺与1,3-二烯的CH官能化/分子内不对称烯丙基化级联反应。在手性吡啶-恶唑啉配体的存在下,使用环境友好的空气作为末端氧化剂,该方案能够以高达83%的产率和高达96%的对映选择性合成手性3,4-二氢异喹诺酮。
