Unlike the situation with the Eubacteria, the archaeal Hyp protein trees are surprisingly inconsistent with one another. This may be because the relatively few sequences available derive from widely divergent organisms. 

Furthermore methods for combining the fermentation of lactic acid and production of chemical sequence products derived from lactic acid are required for the development of intermediates and speciality chemicals. A worthwhile approach could be the direct fermentation on organic lactates, such as substituted aminium lactates. 

Nitroalkenes react with lithium dianions of carboxylic acids or with hthium enolates at -100 °C, and subsequent treatment of the Michael adducts with aqueous acid gives y-keto acids or esters in a one-pot operation, respectively (Eq. 4.52).66 The sequence of Michael addition to nitroalkenes and Nef reaction (Section 6.1) provides a useful tool for organic synthesis. For example, the addition of carbanions derived from sulfones to nitroalkenes followed by the Nef reaction and elimination of the sulfonyl group gives a,P-unsaturated ketones (Eq. 4.53).67...
