Anwendung

5-Bromo-1-pentene was used in stereoselective synthesis of 7α-(3-carboxypropyl) estradiol. It was used in preparation of thioacetate 11 of sialic acid having thioglycosidic linkage. It was also used as staring material in recent syntheses of DL-histrionicotoxin and benzophenone-containing fatty acids.

An efficient synthesis of a series of carbosilane dendrimers uniformly functionalized with alpha-thioglycoside of sialic acid was accomplished. The results of a preliminary study on biological responses against influenza virus sialidases using thiosialoside clusters showed that some of the glycodendrimers

The synthesis of (+/-)-histrionicotoxin has been achieved in just nine steps using a two-directional synthesis strategy. Key reactions include a two-directional cross-metathesis, a tandem oxime formation/Michael addition/1,4-prototopic shift/[3 + 2]-cycloaddition cascade, a selective Z,Z-bisenyne formation, and a one-pot N-O and
