Asymmetric Synthesis of Spirocyclic 2-Benzopyrans for Positron Emission Tomography of σ(1) Receptors in the Brain
Sharpless asymmetric dihydroxylation of styrene derivative 6 afforded chiral triols (R)-7 and (S)-7, which were cyclized with tosyl chloride in the presence of Bu(2)SnO to provide 2-benzopyrans (R)-4 and (S)-4 with high regioselectivity. The additional hydroxy moiety in the 4-position was exploited...
