Blass, Benjamin E.,Blattner, Kevin M.,Canney, Daniel J.,Gao, Rong,Gordon, John C.,Pippin, Douglas A.
, p. 337 - 349 (2022/01/19)
The sigma-2 (σ2) receptor was discovered nearly 40 years ago and was recently identified as the Transmembrane Protein 97 (TMEM97, also known as MAC30 (Meningioma-associated protein)). Aberrant σ2 activity has been linked to diseases

experimental part, p. 1039 - 1045 (2010/04/29)
The stereoselective total synthesis of the nonenolide, (+)-stagonolide B is described. The key steps involve epoxide homologation, hydrolytic kinetic resolution and ring-closing metathesis.
Ring-conformer effects of the cyclopropyl group: First use of trans-(2r,3r)-cyclopropanecarbaldehydes as electrophiles in diastereoselective baylisihillman reaction

scheme or table, p. 2605 - 2608 (2010/03/03)
trans-(2R,3R)-Cyclopropanecarbaldehydes are used as novel electrophiles in the Baylis-Hillman reaction to afford adducts in good yields (75-85%) and diastereoselectivities (60-90%).
Synthesis of α- and β-substituted aminoethane sulfonamide arginine- glycine mimics
Lowik, Dennis W.P.M.,Liskamp, Rob M.J.
, p. 1219 - 1228 (2007/10/03)
In this paper we present a synthesis of both α- and β-substituted aminoethane sulfonamide arginine mimics. The α-substituted sulfonamides were obtained starting from an alkene, whereas the β-substituted sulfonamides were derived from an amino acid derivative.
Pentacoordinate organoaluminum chemistry: Catalytic efficiency of Me3Al in the epoxide cleavage with alkynyllithiums

, p. 3328 - 3333 (2007/10/03)
A new and highly effective catalytic method for epoxide alkynylations has been developed that involves the chelation-controlled alkylation of heterosubstituted epoxides with Me3Al via pentacoordinate organoaluminum complexes by taking advantage of the exceedingly high affinity of aluminum to oxygen. For example, reaction of epoxy ether, (1-benzyloxy)-3-butene oxide (1), in toluene with PhC?CLi under the influence of catalytic Me3Al (10 mol%) proceeded smoothly at 0 °C for 5 h to furnish the alkynylation product, 1-(benzyloxy)-6-phenylhex-5-yn-3-ol, in 76% yield [cf. 3% without Me3Al catalyst; 78% with stoichiometric Me3Al under similar conditions]. This represents the first catalytic procedure for the amphiphilic alkylation of epoxides. The participation of pentacoordinate Me3Al complexes of epoxy ethers of type 1 is emphasized by comparing the reactivity with the corresponding simple epoxide, 5-phenyl-1-pentene oxide, which was not susceptible to nucleophile attack of PhC?CLi with catalytic Me3Al under similar conditions. The pentacoordinate complex formation of Me3Al with epoxy ether 1 is characterized by low-temperature 13C and 27Al NMR spectroscopy. This approach is also applicable to the selective alkynylation of tosyl aziridines with adjacent ether functionality, which provides a promising method for amino alcohol synthesis.
Regioselective Opening of Simple Epoxides with Diisopropylamine Trihydrofluoride
Muehlbacher, Manfred,Poulter, C. Dale
, p. 1026 - 1030 (2007/10/02)
Treatment of benzyl ether derivatives of simple aliphatic epoxy alcohols with diisopropylamine trihydrofluoride gave mixtures of the corresponding fluorohydrins in good yields.Steric hindrance is a major factor in determining the regioselectivity of epoxide opening, although electronic effects cannot be ignored.Electronic effects are more dominant with pyridine polyhydrofluoride.
