describe a method for the synthesis of sulfonamides through the combination of an organometallicreagent, a sulfurdioxide equivalent, and an aqueous solution of an amine under oxidative conditions (bleach). This simple reaction protocol avoids the need to employ sulfonyl chloride substrates, thus removing the limitation imposed by the commercial availability of these reagents. The resultant method allows

New substituted 2,2-dimethyl-5-phenoxy-pentanoic acid benzamides which are useful as antiarteriosclerotic agents are disclosed. These compounds elevate the high density lipoprotein fraction of cholesterol, and also lower the low density lipoprotein fraction of cholesterol. They have the following formula:
wherein R1, R2, A and B are various substituents, and k is 0 or 1.
