Specifications

Description

Applications
It is employed in the preparation of 4-methoxytetrahydropyran-4-yl protecting group, synthesis of symmetric tetra substituted methanes. The methyl enol ether is a useful protecting agent for alcohols, e.g. in nucleotide synthesis, with the advantage over 3,4-Dihydro-2H-pyran. It is also employed in a study of the enantioselective alpha-aminoxylation of ketones with nitrosobenzene and L-proline in an ionic liquid. It undergoes condensation reactions in the preparation of dipeptides and spiroimidazolones. It is also employed in wittig reactions for the synthesis of Penicillins and in a ring of vitamin D3

Solubility
Very soluble in water.

Notes
Store away from strong bases and oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
