Chemical understanding is driven by the experimental discovery of new compounds
and reactivity, and is supported by theory and computation that provide detailed
physical insight. Although theoretical and computational studies have generally
focused on specific processes or mechanistic hypotheses, recent methodological
and computational advances harken the advent of their principal role in
discovery. Here we report the development and application of the ab initio
nanoreactor--a highly accelerated first-principles molecular dynamics simulation
of chemical reactions that discovers new molecules and mechanisms without
preordained reaction coordinates or elementary steps. Using the nanoreactor, we
show new pathways for glycine synthesis from primitive compounds proposed to
exist on the early Earth, which provide new insight into the classic Urey-Miller
experiment. These results highlight the emergence of theoretical and
computational chemistry as a tool for discovery, in addition to its traditional
role of interpreting experimental findings.
