title: (S)-(Z)-Methyl 2-[2,3-bis-(benzyl-oxy-carbon-yl)guanidino]-4-methyl-penta-no-ate.
abstract: The title mol-ecule, C(24)H(29)N(3)O(6), has a nearly planar ten-atom C(3)N(3)O(4) core, on account of both N-H groups forming six-membered-ring intra-molecular hydrogen bonds to carbamate carbonyl O atoms. The absolute configuration was determined from resonant scattering of light atoms in Mo Kα radiation, agreeing with the configuration of starting materials.
