Vanishing aromaticity: A chiral ruthenium complex catalyzes the hydrogenation of 2,6‐ or 2,7‐disubstituted naphthalenes to give chiral tetralins with up to 92 % ee. The chiral catalyst is applicable to the regio‐ and enantioselective reduction of 6‐substituted 2‐alkoxynaphthalenes and preferentially hydrogenates the alkoxy‐substituted arene rings.
消失的芳香性:手性钌络合物催化2,6或2,7-二取代的萘的氢化反应,得到手性四氢化萘的ee高达92%。手性催化剂适用于6-取代的2-烷氧基萘的区域和对映选择性还原,并优先氢化烷氧基取代的芳烃环。
