Stereoselective synthesis of anamarine
Tetrahedron, 2004A stereoselective synthesis of the naturally occurring, α,β-unsaturated lactone anamarine is described. The key step was a highly stereoselective aldol reaction of a protected erythrulose derivative with a chiral aldehyde. Another relevant step was an asymmetric aldehyde allylation with a chiral allylborane. The lactone ring was made by means of a ring-

Isoflurane anesthesia is stereoselective
European Journal of Pharmacology, 1992The anesthetic effects of the (+) and (-) isomers of isoflurane were determined in mice. Like the clinically important racemate, both isomers produced dose-dependent increases in anesthetic sleep time. A statistically significant (P less than 0.005, ANOVA) difference in the potencies of these isomers ((+) greater than (-)) was observed.

Stereoselective Synthesis of (+)-Aspidofractinine
The Journal of Organic Chemistry, 2009We describe the synthesis of (+)-aspidofractinine, the enantiomer of a naturally occurring alkaloid of the kopsane family. Key features of the synthesis include a stereospecific cyanate to isocyanate rearrangement on a chiral scaffold, a ring-closing alkene metathesis to cleave the chiral auxiliary, and a chemoselective cyclopropanation to introduce ...
