  Total synthesis of (+)-asperlin

  摘要：

  Syntheses of (+)-asperlin 1 were achieved via two different synthetic routes. 1,2-Addition of alpha-furyl anion to (2R,3S)-2-'butyldimethylsilyloxy-3-chlorobutanal 6 gave (1S,2R,3S)-1-(2-furyl)-2-'butyldimethylsilyloxy-3-chlorobutanol 7, which was converted to the chiral intermediate, (1S,2R,3R)-1-(2-furyl)-2,3-epoxybutanol 8 (37% overall yield from 6) for the synthesis of (+)-1. The second synthesis of (+)-asperlin 1 from (2R,3S)-6 was achieved in 8% overall yield, based on a combination of the indium-assisted stereoselective addition of 3-bromopropenyl acetate 9 to (2R,3S)-6 and the ring closing metathesis (RCM) using Grubbs catalyst.
