A stereoselective asymmetric synthesis of antibiotic (-)-Fumagillol using claisen rearrangement and intramolecular ester enolate alkylation as key steps
(-)-Fumagillol (1), a hydrolysis product of fumagillin, has been synthesized by several group from commercially available 1,2:5,6-di-O-isopropylidene-α-D-allofuranose in a highly stereoselective manner. Chiral...

A steroselective synthesis of (22R, 23R)-methylenecholesterol
The marine sterol (22R, 23R)-methylenecholesterol1 has been synthesized from readily available C-22 steroidal ester2 utilizing an intermolecular acyclic ester enolate alkylation as the key step.

Stereochemical aspects of diels-alder reaction of substituted penta-2,4-dienols and maleic anhydride derivatives
Reaction of diene alcohol5 and maleic anhydride in benzene at either room temperature or reflux proceeds probably through a intermolecular Diels-Alder cycloaddition followed by lactone formation to give adduct6.
