  Highly Efficient and Diastereoselective Synthesis of (+)-Lineatin

  摘要：

  A linear sequence was used to synthesize (+)-lineatin in 14 steps and 14% overall yield from a homochiral 2(5H)-furanone. Key steps of this synthetic approach feature the diastereoselective construction of a cyclobutene through a photochemical [2 + 2] cycloaddition and a regiocontrolled oxymercuration reaction.

  The photochemical [2 + 2] cycloaddition of (S)-4-methyl-5-O-pivaloyloxymethyl-2(5H)-furanone, 5, to vinyl acetate, vinyl pivalate, tert-butyl vinyl ether, 1,1-diethoxyethylene, and (Z)- and (E)-1,2-dichloroethylene has been studied. A practical synthesis of (+)-lineatin from 5 has been developed via the functionalized cyclobutane 6.

  A highly stereoselective and efficient synthetic approach to cyclobutane and cyclobutene derivatives has been developed consisting of a [2+2] photochemical cycloaddition of chiral 2(5H)-furanones to (Z)-1,2-dichloroethylene followed by dihydrodehalogenation or dihaloelimination.

  The [2 + 2] photocycloaddition of acetylene to chiral 2(5H)-furanones was investigated. The influence on the chemical yield and facial diastereoselectivity of the substituent at the stereogenic center and also the effect of a 4-methyl group were evaluated. A mechanistic proposal based on a simple theoretical conformational analysis is presented. Using a C(2)-symmetric bis(lactone) as the substrate
