Case Studies: Organising Proximity, (1949a and c) and ., and . (1951) demonstrated that aspergillic acid has the structure shown in Fig. 1. . (1961) found that the optical configuration of the asymmetric carbon atom of the sec-butyl side chain of aspergillic acid was the same as that of carbon 3 of .-isoleucine.

The most commonly found hydroxylamino compounds are the naturally occurring hydroxamic acids, which are excreted into the medium in amounts sometimes exceeding one gram per liter of culture fluid.

Empirical Insights: Effects of Distance,..., 1948; . and ., 1948). As shown in Fig. 1a, its structure is D-(—)-threo-2-dichloroacetamido-l-p-nitrophenyl-1,3-propandiol (..., 1949; ..., 1949). The compound is thus relatively simple but interesting, for it is one of the few natural products with both an aryl nitro group and organic halogen.
