Nobel in chemistry honors 'greener' way to build molecules

STOCKHOLM (AP) — Two scientists won the Nobel Prize in chemistry Wednesday for finding an ingenious and environmentally cleaner way to build molecules — an approach now used to make a variety of compounds, including medicines and pesticides.

The work of Benjamin List and David W.C. MacMillan has allowed scientists to produce those molecules more cheaply, efficiently, safely and with significantly less hazardous waste.

"It's already benefiting humankind greatly," said Pernilla Wittung-Stafshede, a member of the Nobel panel.
