Abstract
A new catalytic process for the isomerization of asocainol isomers at the 6-position which provides an inexpensive, rapid, and simple method for large scale production of the (R,R) isomer of (R,S) asocainol is asocainol. The (R,R) isomer of (R,S) asocainol is treated with small amounts of a salt and an oxidizing agent at an elevated temperature. The compounds and their pharmaceutically acceptable salts are useful as potent antiarrhythmic agents and local anesthetics.
