Nerol, acyclic monoterpene alcohol, has been stereoselectively synthesized using as an intermediate the unsaturated hydroxylic acid VI, in which the carboxyl and the hydroxymethyl groups are evidently in the cis-relation.

Hydromagnesiation of prop-2-ynylic alcohols proceeds with stereo- and regio-specificity, affording, under mild conditions, the alkenylmagnesium halides (5) in almost quantitative yields, thus providing a novel and simpleroute to terpenoids.
Described herein are neutral prodrugs of phosphorus-containing inhibitors of farnesyl transferase that include one or more phosphate fragments or analogs of phosphate fragments. Analogs of phosphate fragments include various linkers other than oxygen connecting the phosphate fragment to the remaining portion of the drug, such as but not limited to linkers forming phosphoramidates, phosphonates, difluorophosphonates, phosphordiamidates, and the like.
