An oxetane intermediate during a direct aldol reaction was trapped with an internal aryl group to yield trans-tetraline products. The contribution of the oxetane intermediate was confirmed by 18O-isotope labeling experiments.
<p>The substitutions at the 2′- and/or 6′-positions of the quinoline ring of cinchonidine reduce both the intrinsic enantioselectivity and adsorption strength for the enantioselective hydrogenation of α-phenylcinnamic acid over Pd/C.</p>
Alkylideneallyl cation generated from Lewis acid-mediated ring-opening reaction of alkylidenecyclopropanone acetal was employed for the reaction with siloxyalkenes to give [3 + 2] cycloaddition and acyclic addition products. All the products are t...

Alkenylboronic esters having an acyloxy, alkoxy, or methoxycarbonyl group were employed for the reaction with (diacetoxyiodo)benzene in the presence of BF(3)center dot OEt(2) to provide the alkenyliodonium tetrafluoroborates with inversion of conf...
