  • Synthesis of α-amino acids with β,γ-unsaturated side chains
    作者:Arlindo L. Castelhano、Stephen Horne、Gregg J. Taylor、Roland Billedeau、Allen Krantz

    日期:1988.1
    α-Amino acids with allenyl, vinyl, and acetylenic side chains can be synthesized using non-enolate based strategies. The ester enolate-Claisen rearrangement applied to propargylic esters of N -protected α-amino acids ie of limited utility since only poor yields of allenic product are obtained with the N-Boc glycine esters, the system which give the most reproducible results. However, α-allenyl-α-amino

  • Rhodium-Catalyzed Reaction of 1-Alkenylboronates with Aldehydes Leading to Allylation Products
    作者:Hiroshi Shimizu、Tomohiro Igarashi、Tomoya Miura、Masahiro Murakami
    DOI:10.1002/anie.201105148
    日期:2011.11.25
    Synthetic equivalents: 1‐Alkenylboronates perform the role of an allylating reagent. Their reaction with aldehydes in the presence of a cationic rhodium(I)/dppm catalyst results in a highly diastereoselective production of anti‐configured homoallylic alcohols (see scheme; Bpin=4,4,5,5‐tetramethyl‐1,3,2‐dioxaborolanyl).
