  • Stereospecific palladium-catalyzed 1,4-acetoxychlorination of 1,3-dienes
    作者:Jan-E. Bäckvall、Ruth E. Nordberg、Jan-E. Nyström

    日期:1982.1
    Palladium-catalyzed oxidation of 1,3-dienes in acetic acid in the presence of LiCl and LiOAc produces 1-acetoxy-4-chloro-2-alkenes in high selectivity. The 1,4-adducts were stereo- and regioselectively functionalized.

    (η3-1- and 2-Trimethylsiloxyallyl)Fe(CO)2NO complexes were prepared by the reaction of the corresponding siloxyallylic halides with Bu4N[Fe(CO)3NO]. These complexes reacted with both of carbon nucleophiles and carbon electrophiles preferentially at the less hindered sites of the allylic ligands. In these reactions, (η3-1-trimethylsiloxyallyl)Fe(CO)2NO complexes served as synthetically equivalent synthons

  • Synthesisi of Erythrina and Related Alkaloids. Part XLVII. General Method for Synthesis of Erythrinan and Homoerythrinan Alkaloids (1): Synthesis of a Cycloerythrinan, as a Key Intermediate to Erythrina Alkaloids, by Pummerer-Type Reaction.

    A new synthetic route to Erythrina alkaloids by formation of ring C utilizing a Pummerer-type intramolecular cyclization was developed. The N-(2-phenylthioethyl)-dioxopyrroline (3) was converted to 13 in five steps with satisfactory overall yield (69%) by means of [2+2] photocycloaddition followed by 1, 3-anionic rearrangement as crucial reactions. Treatment of the sulfoxide (13) with trifluoroacetic anhydride gave the cyclization product, 11-phenylthioerythrinan (15), in 87% yield. This was converted to the cycloerythrinan (22) by reductive elimination of the PhS group, thus constituting a formal total synthesis of (±)-erysotrine.
