The Michael addition of primary aliphatic nitro compounds to alpha,beta-unsaturated enones, performed in aqueous media, provides the one-pot synthesis of 1,4-diketones, 1,4-diols, delta-nitroalkanols, and hydroxytetrahydrofurans, respectively, by the appropriate choice of the reaction conditions.

The Pd-catalyzed asymmetric intramolecular dearomatization of pyrroles via the Heck reaction in the presence of commercially available Pd(OAc)2 and the Feringa ligand is described. Diverse pyrroline derivatives were obtained in excellent yields (up to 99%) with high enantioselectivity (up to 96% ee). The reaction features a wide substrate scope, relatively mild conditions, and useful transformations
synthetic route to C2-symmetric chiral 1,4-diols based on the borane-mediated oxazaborolidine-catalysed reduction of 2-ene-1,4-diones (2), of 2-yne-1,4-diones (3), and/or of Co-complexed diketones 4 is described. Good to excellent enantio- and diastereoselectivities have been obtained in the reduction of diketones 3 and 4, catalysed by oxazaborolidines 6 and 5, respectively.
An efficient method for the preparation of C2-symmetric, chiral alk-2-ene-1,4-diols (4) has been achieved, based on the borane-mediated reduction of symmetric alk-2-ene-1,4-diones (2) in the presence of oxazaborolidine (R)-1. In general, the presence of the double bond in 2 has been beneficial (compared with the related saturated 1,4-diketones 3) not only as far as the stereoselectivity in the reduction
