    Synthesis of Filibuvir. Part I. Diastereoselective Preparation of a β-Hydroxy Alkynyl Oxazolidinone and Conversion to a 6,6-Disubstituted 2H-Pyranone
    摘要:
    This is the first in a series of three papers describing the identification and development of a commercial synthesis of filibuvir (1). This contribution describes development of an Evans aldol reaction to control the tertiary alcohol stereocenter, a challenging variant of that strategy in that both reacting partners were nonstandard (acetate etiolate and ketone electrophile). A sequence consisting of Sonogashira coupling, acylation and hydrogenation delivered acetate 24, and Dieckmann cyclization provided beta-keto lactone 2.

    Asymmetric cascade double Michael additions to construct 2′‐substituted 3,3′‐spirooxindoles by using a chiral guanidine organocatalyst has been developed. A series of spirooxindole derivatives containing dihydrofuran or pyrrolidine subunits were obtained with good to excellent diastereo‐ and enantioselectivities. The method showed great tolerance of a number of aromatic and aliphatic alkynones. The

    Combining established two electron nucleophilic catalysis of organophosphines with photoredox organocatalysis has allowed the discovery of a mechanistically unusual Giese coupling reaction. In addition to addressing a limitation in traditional photoredox coupling with electron-poor alkynes these studies demonstrate the viability of reaction designs that merge traditional nucleophilic phosphines organocatalysis
