The carboxylation and epoxidation reactions are said to be coupled.
2.
Transition metal hypochlorites are generally unheard of, although hypochlorite will briefly coordinate to a Mn ( III )-salen complex during the Jacobsen epoxidation reaction.
3.
This mechanism, which was originally proposed by John Groves to explain porphyrin-catalyzed epoxidation reactions, is commonly referred to as a " side-on perpendicular approach ".
4.
Compounds containing dioxirane as a functional group, called "'dioxiranes "', often possess better stability and are used in organic synthesis as oxidizing reagents, most notably as the key catalytic intermediate in the Shi epoxidation reaction.
5.
Using a base mediated epoxidation reaction, structure 3 was achieved, which led to structure 4 after exhaustive hydroxymethylation in the presence of DBU . The formation of structure 4 is particularly impressive it not only forms two important C-C bonds in one step, but also occurs in quantitative yield.
6.
They studied the action of a P450 enzyme contained in the pathway ( TamI ) by purifying it from a recombinant host, and saw, " in vitro ", that it can oxidize multiple oxidation steps, namely tirandamycin A into tirandamycin B and tirandamycin D into tirandamycin A, which correspond to two hydroxylations and one epoxidation reaction.
