• β-Aryl-α-nitro-α,β-enals as Heterodienes and Dienophiles

  As demonstrated with the beta-(2-furyl)-substituted analogue 1b, beta-aryl-alpha-nitro-alpha,beta-enals (1) behave as heterodienes against enamines and enol ethers using their enal unit (e.g., 1b -> 12). alpha-Nitro-alpha,beta-enals can act as well as highly reactive dienophiles to render adducts endowed with nitrogenated quaternary centers (e.g., 1b -> 15a). A hetero-Diels-Alder (HDA)/Diels-Alder (DA) sequence from 1b also proved feasible on serial treatment with ethyl vinyl ether and Danishefsky's diene (1b -> 14).

  The invention relates to the synthesis of polyoxygenated nitrogen systems, comprising reactions between enamines of 1,3-dioxan-5-ones and nitroolefins. More specifically, the invention relates to the reaction between enamines having formula II which are derived from 1,3-dioxan-5-ones I and nitroolefins having formula III. In this way, novel polyoxygenated nitrogen systems are generated having formula IV and V, which, as they are or following simple transformations, constitute synthetic intermediates and/or analogues of different systems of proven biological/pharmacological interest, such as certain antibiotics, or tetrodotoxin, pancratistatin or the analogues thereof. The aforementioned reactions involve the use of enamines II in Michael-type addition reactions and in direct annealing processes with double acceptor systems at relative positions 1, 3. Said N acceptors include nitroolefins III, wherein R═CHO (alphanitroenals). The invention also relates to the preparation thereof, which is based on the oxidation of the corresponding precursor alcohols VII, and the use of same in annealing processes.
