A novel palladium-catalyzed ring-opening reaction of oxabicyclic alkenes with arylsulfonylhydrazides was first developed. In this work, we provide an efficient one-pot reaction to afford the corresponding cis-2-aryl-1,2-dihydronaphthalen-1-ols and 2-aryl-naphthalenes in moderate to excellent yields (up to 95%) under an open-air condition. Various types of functional groups attached to the substrates

Palladium-catalyzed syn-stereocontrolled ring-opening reactions of oxabenzonorbornadienes with a wide range of sodium arylsulfinates were investigated, affording the desired products in good to excellent yields under an air atmosphere. This protocol provides a low-cost new viable and convenient method toward the synthesis of cis-2-aryl-1,2-dihydronaphthalen-1-ol with good functional group tolerance
The chiral phosphine-containing palladacycle, synthesized easily from H-MOP, showed its high catalytic activity as well as asymmetric induction ability in ring-openingreaction of oxabicyclic alkenes with arylboronic acids, providing corresponding products in high yields and high ee.

The asymmetric ring opening reactions of bicyclic alkenes with boronic acids were accomplished by using a highly active palladium/zinc co-catalytic system that was suitable for both azabenzonorbornadienes and oxabenzonorbornadienes, which were transformed to the corresponding chiral hydronaphthalene products in high yields (up to 99%) and high optical purities (up to 98% ee). The reaction protocol

Water‐promoted palladium‐catalyzed asymmetric ring‐opening (ARO) reaction of oxabenzonorbornadienes with a wide variety of alkoxysilanes has been developed in a one‐pot fashion, yielding cis‐1,2‐dihydronaphthalen‐1‐ols in favourable yields (up to 98%) with gratifying enantioselectivities (up to 98% ee) under mild conditions. To the best of our knowledge, it represents the first example in the ring‐opening
