DIMETHYLBUTYL ACETATE (108-84-9) Forms explosive mixture with air (flash point 113°F/4.5°C). Violent reaction with strong oxidizers. Incompatible with sulfuric acid, nitric acid, caustics, aliphatic amines, isocyanates. Will swell rubber, and can dissolve certain coatings. 

Unsaturated compounds are obtained in good yield and often without isomerization by pyrolysis of esters of the requisite alcohol. These pyrolyses generally proceed with considerable stereoselectivity, yielding mostly the cis-olefin. A review of pyrolytic cw-eliminations has been provided by DePuy and King.23 The experimental technique is very simple the ester is heated as liquid or vapor at 300-500°. Working up of the product is also simple since neither a solvent nor another reactant is present. Pyrolysis of 1,2-dimethyl-propyl acetate at 500° gives pure 3-methyl-1-butene in 72% yield pyrolysis of 1,3-dimethylbutyl acetate also proceeds only in one direction, yielding 4-methyl-l-butene,24 and it is to be noted that in these cases olefin formation does not follow Saytzeff s rule ...

Figure 6. The effects of 2.6 mM 3,3 -dimethylbutyl acetate on the concentration-dependent inhibition of AChE by ANTX-A(S). Conditions and symbols are the same as Figure 5.

Because the ACh receptor does not hydrolyse acetylcholine, the esteratic site of acetylcholinesterase (see Fig. 12.3) must be absent. Other fundamental differences in the two sites are indicated by the following (a) dimethylbutyl acetate 12.66) is a good substrate for the enzyme, but barely activates the receptor which requires a basic group for marked activity (b) muscarine is not a substrate for the enzyme and yet it is a powerful agonist for the muscarinic receptor (c) di-isopropyl phosphorofluoridate (isoflurophate) 13.26) binds to the active site of AChase but not to an ACh receptor (d) acetyl-bungarotoxin specifically binds to the ACh nicotinic receptor but not to the enzyme. 

When it was foimd that 3,3-dimethylbutyl acetate (13.45) and acetylcholine are equally easily hydrolysed by acetylcholinesterase, it was realized that the van der Waals forces of the methyl-groups (surrounding the cation of acetylcholine) could be just as important as a positive charge in binding the natural transmitter to the enzyme (Whittaker, 1951). 

The equilibrium distance of the quaternary nitrogen atom of acetylcholine from the negatively charged group of the receptor has been calculated as 3.29 A from the difference in free energy of the receptor-interaction of (a) acetylcholine 13.44) (b) dimethylbutyl acetate (13.43). The...
