(Chemical Equation Presented) The first general methodology for the gram-scale preparation of previously overlooked β-(hetero)aryl-α- nitro-α,β-enals (3) is reported. Condensation of (hetero)aromatic aldehydes with 2-nitroethanol gave the E-isome

The radical-based site-selective oxidation of 2-hydroxyethyl acetals and the metal(Zn,Ti)-induced 2-propynylation of aldehydes can both be carried out successfully on highly functionalized oxygenated substrates, as demonstrated in the context of a sy

As demonstrated with the β-(2-furyl)-substituted analogue 1b, β-aryl-α-nitro-α,β-enals (1) behave as heterodienes against enamines and enol ethers using their enal unit (e.g., 1b → 12). α-Nitro-α,β-enals can act as well as highly reactive d

A novel, highly stereocontrolled formal [3 + 3] annulation of beta-aryl-alpha-nitro-alpha,beta-enals with the enamine derived from 2,2-dimethyl-1,3-dioxan-5-one and pyrrolidine afforded protected nitrocyclitols with five newly created stereocentres a

We describe a highly efficient and highly enantioselective Hantzsch ester mediated conjugate transfer hydrogenation of β,β-disubstituted nitroolefins that is catalyzed by a Jacobsen-type thiourea catalyst.
