Application

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

Alkylation of 3,17 beta-bis(2-trimethylsilyl)ethoxymethyl-1,3,5(10) estratriene-6-one (2) with 5-bromo-1-pentene using NaHMDS in THF afforded 3,17 beta-bis(2-trimethylsilyl)ethoxymethyl-7-alpha-(4'pentenyl)-1,3,5(10) estratriene-6-one (3) in excellent stereoselectivity (> 95% epimeric excess). Functionalization of the side chain in compound 3 was accomplished via ozonolysis, oxidation and esterification to

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

Several divinylic mesogenic monomers were synthesized based on coupling the monomer 4-(4-pentenyloxy)benzoic acid with chlorohydroquinone, 2,5-dihydroxy- acetophenone, methylhydroquinone or 2-methoxyhydroquinone. This resulted in novel mesogens of phenylene esters with different lateral substituent groups. The effect of the lateral substituent group
