  Diastereoselective Ring-Closing Metathesis in the Synthesis of Dihydropyrans

  摘要：

  An investigation into the factors influencing the diastereochemical outcome of the ring-closing metathesis based synthesis of dihydropyrans is presented in this paper. Divinyl carbinols derived from alpha-hydroxy carboxylic acid esters are elaborated to trienes with two diastereotopic vinyl moieties. Depending on the steric demand of the oxo substituent of the divinyl carbinol moiety (either unprotected OH, TBDMS, or benzyl ether) different diastereomers are preferrably formed upon ring-closing metathesis. An extension to diastereoselective double ring-closing metathesis in the formation of spirocycles has also been investigated.

  presence of lithium dialkylamides to functionalized 2,3-dihydropyrans or 2,3-dihydrofurans, respectively, is described. The regiochemical outcome of the reaction can be influenced by the relative configuration of the starting epoxides and the steric demand of the base. The 2,3-dihydropyrans obtained were converted stereoselectively to difunctionalized 3,4-dihydropyrans by the carbon-Ferrier reaction, or to

  α-Hydroxy carboxylic acids and their derivatives are naturally occurring starting materials for the synthesis of functionalized tetrahydropyrans using ring closing metathesis and base induced epoxide rearrangement as key steps. (S)-Lactic acid methyl ester has been used as the starting material for the preparation of enantiomerically pure 6-desoxy C-glycoside precursors.
