An extremely mild acetate pyrolysis reaction. novel synthesis and x-ray structure determination of 1-azaspiro(5.5)undecane derivatives

TL;DR: In this paper, the azaspiro oxo-urethane (4), readily available from naphthalene, is reduced to the amino-alcohol whose diacetate (6), the structure of which was determined by X-ray crystallography, undergoes acetate elimination in refluxing toluene to yield the N-acetylazaspiroundecene (7).
Journal ArticleDOI

Synthesis of 4,4-Disubstituted Cyclohexenones. Part 3. The Reaction of 1,3-Bis(trimethylsilyloxy)cyclohexa-1,3-dienes with Dienophiles. An Unexpected Rearrangement of the Adducts from the Reaction with 2-Chloroacrylonitrile.

TL;DR: The cycloaddition of 2-chloroacrylonitrile to diene in toluene, hexane, or dichloromethane in the presence of Lewis acids such as Me2AlCl or TiCl4, occurs in high yield at −78 °C with great syn-selectivity and a slight preference for the exo-nitrile stereochemistry as discussed by the authors.
Journal ArticleDOI

Enantioselective Synthesis of (S)-γ-Acetylenic γ-Aminobutyric Acid (GABA) and (S)-trans-γ-Butenynyl GABA.

TL;DR: In this paper, the enantioselective syntheses of (S)-γ-acetylacetylenic γ-aminobutyric acid (GABA) and the (E)-butenynyl analogue (2) by phthalimide displacement of the homochiral prop-2-ynylic alcohols (6) and (11)[generated from the acetals (3, and (9, respectively], are reported.
