  • One-flask, consecutive [3,3]- and [2,3]-sigmatropic rearrangements for conversions of propargylic alcohols into 2-carbon-extended 4-oxo-2-alkenoate esters. Use of a new 1-chloro-1-ethoxy-2-sulfinylethylene

    Seven differently substituted primary and secondary propargylic alcohols are shown to react with (arylsulfinyl) vinylic chloride 1a at 100-degrees-C for 1 h sequentially via a [3,3] sigmatropic rearrangement and then a [2,3] sigmatropic rearrangement to form 4-oxo-2-alkenoates 8a-8e and 9a and 9b in 52-80% yields. This one-flask, intramolecular carbon-carbon bond-forming process represents a simple and convenient method not only for regiospecific gamma-attachment onto a propargylic alcohol of a two-carbon (ethoxycarbonyl)methylene unit but also for alpha --> beta transposition of oxygen. The synthetic utility of this procedure is illustrated further by eqs 2 and 3 for preparation of regiospecifically functionalized carbocycles and heterocycles. Also, two different primary allenic allylic alcohols are shown to produce directly two-carbon extended 3-(hydroxyalkyl)-2,4-pentadienoates (E)-18 and the corresponding unsaturated lactones (Z)-18 in 37-41% yields.

    Stereoselective functionalization at C-9 of retinal based on the use of the C4+X-unit is described. A sequential linkage of C4+X-units (X=Cl, Br, and I) with ylide 8 (C10) and phosphonate 12 (C5)selectively gave 9-trans-19-nor-9-Cl, Br, and I-retinal derivatives.
