2,2-dimethyl-1,3-dioxolane-4-carboxylic acid derived chiral building blocks were prepared from substituted α,β-unsaturated acids with high enantiomeric purities by enzymatic hydrolysis of their n.butyl esters.

Helmanticine, a new phenylpropanoid esterified by angelic and 2,3-dihydroxy-2-methylbutyric acids, was isolated from Thapsia villosa and its full structure established by spectroscopic methods and chemical transformations.Hydrocarbons, 12-nonacosanone, sitosterol and latifolone were also isolated. Key Word Index - Thapsia villosa; Umbelliferae; phenylpropanoids; helmanticine; latifolone; 12-nonacosanone.
