  名称：

  Regio-, stereo-, and enantioselective synthesis of cyclobutanols by means of the photoaddition of 1,3-dioxin-4-ones and lipase-catalyzed acetylation

  摘要：

  Homochiral cis-2-hydroxymethylcyclobutanols, their all cis 3-methyl, and 4-hydroxymethyl derivatives were synthesized from 1,3-dioxin-4-ones via cyclobutane ring formation by [2+2]photocycloaddition, dioxanone ring cleavage, and reduction, followed by lipase-catalyzed kinetic resolution of the resulted cyclobutanols. The chiral cyclobutanols thus obtained have been converted to the corresponding gamma-lactones which are potential precursors for a series of biologically active compounds.
