General Description

(2Z)-1,1,4,4-tetramethoxybut-2-ene is a chemical compound with the molecular formula C10H18O4. It is a type of butene, which is a hydrocarbon with a carbon-carbon double bond in the 2 position. The "2Z" designation indicates the stereochemistry of the double bond, meaning that the two highest priority substituents are on the same side of the double bond. The presence of four methoxy (CH3O) groups in the molecule makes it a methoxybutene. (2Z)-1,1,4,4-tetramethoxybut-2-ene may be used in organic synthesis as a reagent or intermediate, but its specific uses and applications would depend on its properties and reactivity.

REACTION OF ALKOXYFURAN AND ALKOXYPYRANS WITH ALCOHOLS IN ACID MEDIUM

The acetals of fumaraldehyde and glutaraldehyde are respectively formed when 2,5-dialkoxy-2,5-dihydrofuran and 2-alkoxy-2,3-dihydropyrans are reacted with alcohols in acid medium.The monomethyl-substituted alkoxypyrans are cleaved to glutaraldehyde acetals with much greater difficulty than the unsubstituted derivatives.A 2-alkoxy-3,3-dimethylpyran and 2,5-dialkoxy-2-methylpyran do not give the corresponding acetals.The stability of the methyl-substituted alkoxypyrans is caused by the fact that the methyl groups shield the oxygen of the pyran ring, thus preventing the addition of a proton to the oxygen of the ring.The reason for the resistance of a 2,5-dialkoxy-2-methylfuran to alcoholysis was not ascertained.A mechanism is given for the opening of alkoxy-2,3-dihydropyrans to glutaraldehyde acetals.
