  Synthesis and stereochemical assignment of geraniol- and nerol-derived Cygerol enantiomers

  摘要：

  The enantiomers (up to 99% ee) of both geraniol- and nerol-derived 2-cyclohexyl-5,9-dimethyldeca-4,8-dienoic acid, the active ingredient of the wound healing medication Cygerol, were prepared via a low-temperature alkylation, basic hydrolysis, derivatization with (S)-4-benzyloxazolidin-2-one and chromatographic separation steps. The absolute configuration of stereocenters in the antipodes having an (E)- or (Z)-geometry of the internal double bond was determined based on characteristic H-1 NMR signals of the corresponding (S)-4-benzyloxazolidin-2-one-derived imides and on conversion to the known diethyl (S)-2-cyclohexylsuccinate and (S)-2-cyclohexylbutane-1,4-diol with reported specific rotations.

  Nitroalkanes as a new source of 2-alkylidene-1,4-diols, in two steps

  摘要：

  A variety of 3-alkylidene-1,4-diols have been conveniently prepared, in two steps, by conjugate addition of a nitroalkane to the appropriate enedione derivatives under basic conditions (DBU), followed by chemoselective reduction (LiAlH4/Et2O) of the carbonyl functionalities of the Michael adduct, obtained after elimination of nitrous acid.

  structures, as well as solvent, affect the overall yield and enantiomeric excess of the reaction product - 3-alkylsubstituted aluminacyclopentanes. The reaction of terminal alkenes with AlEt3, catalyzed by complex 1, in hydrocarbon solvents gives predominantly S-enantiomers of cyclic organoaluminum compounds with enantiomeric excess up to 37%. Complex 2 shows smaller stereoinduction effect and provides

  The disclosure describes a method for the preparation of chiral 1,3-aminoalcohols in high optical purity. The method combines the stereoselective oxidation of a 1,4-diol to a gamma-lactone using an alcohol dehydrogenase, the conversion of the gamma-lactone to the corresponding 4-hydroxyamide, 4-hydroxyhydroxamic acid, or 4-hydroxyhydrazide, and stereospecific rearrangement of the 4-hydroxyamide, 4-hydroxyhydroxamic acid, or 4-hydroxyhydrazide to the corresponding chiral 1,3-aminoalcohol.

  The disclosure describes novel precursors for the preparation of chiral 1,3-aminoalcohols. The precursors are chiral 4-hydroxycarboxamides, 4-hydroxyhydroxamic acids, or 4-hydroxyhydrazides produced from chiral gamma-lactones, which in turn are derived from 1,4-diols by stereoselective oxidation. The chiral 4-hydroxycarboxamides, 4-hydroxyhydroxamic acids, or 4-hydroxyhydrazides are converted into chiral 1,3-aminoalcohols by stereospecific rearrangement.
