The method of Kim et al.[89-93] starts from the synthesis of the three-carbon phosphonium salt according to the modified method of Corey et alJ94,95] The Wittig reaction of the phosphonium salt with a Z-protected a-amino aldehyde using potassium hexamethyldisilazanide provides the ds-alkene without racemization. Efficient hydrolysis of the orthoester without double bond migration is achieved by acidolytic hydrolysis with aqueous hydrochloric acid in tert-butyl alcohol under reflux conditions. Then, an a-amino acid methyl ester is coupled. The desired epoxide product is obtained by treatment with 3-chloroperoxybenzoic acid. The epoxidation reaction is stereoselective and predominantly provides one isomer (R,S S,R = 4-10 1). The trans-epoxide can also be prepared using a trans-alkene-containing peptide. A representative synthetic procedure to obtain the ds-epoxide isostere is detailed below. 

Arylethynylations of potassium benzotriazolate with iodonium tosylates 24 in THF/ -BuOH/CH2C12 have also been reported [149,150]. However, when the terf-butylethynyl salt 25 was used instead, insertion of the intermediate alkyli-denecarbene into the O-H bond of tert-butyl alcohol preempted rearrangement. 

The amide group is readily hydrolyzed to acrylic acid, and diis reaction is kinetically faster in base than in acid solutions (5,32,33). However, hydrolysis of N-alkyl derivatives proceeds at slower rates. The presence of an electron-with-drawing group on nitrogen not only facilitates hydrolysis but also affects the polymerization behavior of diese derivatives (34,35). Widi concentrated sulfuric acid, acrylamide forms acrylamide sulfate salt, die intennediate of the former sulfuric acid process for producing acrylamide commercially. Further reaction of the salt widi alcohols produces acrylate esters (5). In strongly alkaline anhydrous solutions a potassium salt can be formed by reaction with potassium / Y-butoxide in tert-butyl alcohol at room temperature (36). 

Reacts with vapors of sodium with luminescence at about 260°C. Reacts explosively with thionyl chloride or potassium reacts violently with hexafluoro isopropylidene, amino lithium, ammonia, and strong acids reacts with tert-butyl azidoformate to form explosive carbide reacts with 24-hexadiyn-l, 6-diol to form 2, 4-hexadiyn-l, 6-bischloro-formate, a shock-sensitive compound reacts with isopropyl alcohol to form isopropyl chloroformate and hydrogen chloride thermal decomposition may occur in the presents of iron salts and result in explosion. 

Molybdenum-based catalysts are highly active initiators, however, monomers with functionalities with acid hydrogen, such as alcohols, acids, or thiols jeopardize the activity. In contrast, ruthenium-based systems exhibit a higher stability towards these functionalities (19). An example for a molybdenum-based catalyst is (20) MoOCl2(t-BuO)2, where t-BuO is the tert-butyl oxide radical. The complex can be prepared by reacting M0OCI4 with potassium tert-butoxide, i.e., the potassium salt of terf-butanol.
