Anaerobic growth of the bacterium strain HxN1 with n ‐hexane gives nearly equal amounts of (2 R ,1′ R )‐ and (2 S ,1′ R )‐(1‐methylpentyl)succinate, which are formed by the radical addition of the hydrocarbon to fumarate (see scheme). The highly selective attack on the pro‐ S hydrogen atom at C2 of n ‐hexane is associated with inversion of the configuration at C2 during binding to fumarate and exhibits isotopic discrimination against a C 2 H bond.
