3-Hydr-oxy-5,5-dimethyl-2-(2-oxo-propyl)cyclo-hex-2-enone
Abstract:
The title compound, C(11)H(16)O(3), was obtained by reaction of dimedone, 5,5-dimethylcyclohexane-1,3-dione, and α-chloro-acetone. The cyclo-hexenone ring exhibits an envelope conformation with puckering amplitudes Q = 0.433 (2) and Φ = -109.0 (3)°. The 2-oxopropyl fragment is almost perpendicular to the cyclo-hexa-none ring [dihedral angle = 77.72 (8)°]. In the crystal, the mol-ecules are linked to each other through O-H⋯O hydrogen bonding, building a chain parallel to the b axis.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
