Organic Chemist Receives Top Young Canadian Scientist Prize
A University of Alberta organic chemist has been named the 2008
winner of the prestigious Steacie Prize for outstanding scientific
research carried out in Canada. The prize is one of Canada's most
prestigious science awards encompassing a wide range of disciplines
including mathematics, engineering, chemistry, physics, and biology.
Dr. Dennis Hall is an organic chemist working on applications
of compounds known as boronic acids and esters. While today's chemists
can make virtually any molecule they choose, the real challenge is
figuring out which molecule will serve a useful, specific purpose, then
finding a way to produce that compound efficiently, says Hall. Doing so
could save millions of dollars in drug development or improve current
industrial processes.
A mature field, new reactions in organic chemistry are not
common. However Hall and his team have uncovered new ways to activate
organic molecules to make them undergo new reactions, resulting in
significant new uses for these compounds while also making major
theoretical contributions.
One of Hall's recent discoveries is that certain boronic acids
are particularly good catalysts for making amides under mild conditions
at room temperature (amides are important compounds whose functions
include bonding peptides together, which in turn form proteins). Amides
appear in more than a quarter of all pharmaceutical drugs, but
traditional methods to manufacture them are complicated and generate a
lot of waste, some of it toxic. Hall's work helps further efforts of
making chemistry "greener", more environmentally friendly by increasing
the efficiency of chemical processes and producing less waste.
"It is really worthwhile to improve known reactions with boron
chemistry because it is a less toxic element than many other elements,"
he said.
Hall admits 2008 was a bit of a "golden year". Early in the
year he received the Merck Frosst Centre for Therapeutic Research Award
from the Canadian Society of Chemistry, which recognizes distinguished
contributions in the fields of organic chemistry or biochemistry while
working in Canada. He then received the NSERC E.W.R. Steacie Memorial
Fellowships - one of Canada's premier science and engineering research
awards.
"I am always pleased to see organizations that recognize and
fund basic science," commented Hall. "While I'm not making the drugs
that will be on the market in two to three years, I'm helping build the
foundation for those drugs to be made. Organic chemistry is a major
contributor to the large increase of life expectancy in the past
century, and I feel that the Steacie Prize recognizes the importance of
investing in this field".
The Steacie Prize
- worth $15,000 - is handed out each year and recognizes exceptional
contributions from a scientist or engineer of 40 years of age or less.
Winners are selected by a panel appointed by the E.W.R. Steacie
Memorial Fund, a private foundation dedicated to the advancement of
science and engineering in Canada. Previous University of Alberta
recipients of the Steacie Prize include N.J. Dovichi (Chemistry, 1991),
B.D. Sykes (Biochemistry, 1982), and G. Rostoker (Physics, 1979).
With all the recognition, Hall is grateful to the colleagues who nominated him, and points out his success is a team effort.
"There is nothing more satisfying than writing a good paper
with a student and seeing their happy face when it gets accepted in a
journal," he explained.
