Improved procedure for the enantiometric synthesis of 1-hydroxy/acetoxy-2,6-diaryl-3,7-dioxabicyclo[3.3.0]octane lignans: Total syntheses of (+)-paulownin, (+)-phrymarin I and (+)-phrymarin II

Short enantiomeric syntheses of the 1-hydroxy/ acetoxy-3,7-dioxabicyclo[3.3.0]octane lignans, (+)-paulownin, and (+)-phrymarin I and II, were accomplished by starting from the chiral synthon, (R)-(+)-3-hydroxybutanolide, and employing photocyclization as the key step.
