Abstract

The title compound 8 has been synthesized in a one-pot reaction of 4'-(dimethy1amino) benzoin (4) with 2-propanone and NH,. The preparation of the intermediate 4 from 3 is the first example of an acid-catalyzed transformation of the stable benzoin 3 into the corresponding less stable benzoin 4. Structures and yields of various by-products occurring under different reaction conditions during the synthesis of 8 from 4 are given. The 0-atom ...
