Fed Official to Head Amex: The American Stock Exchange said its board of governors elected Richard F. Syron, president of the Federal Reserve Bank of Boston, to become its new chairman starting April 1. Syron, 51, replaces James Jones, who last summer became U.S. ambassador to Mexico. Jules Winter, the exchange’s chief operating officer, has served as acting chief executive. Syron has spent much of his career with the Fed, both in Washington and Boston. He also served as deputy assistant Treasury secretary in 1979 and 1980. In 1981 and early 1992, Syron worked as an assistant to then-Fed Chairman Paul Volcker.
