Miconazole is an imidazole antifungal agent, developed by Janssen Pharmaceutica, commonly applied topically to the skin or tomucous membranes to cure fungal infections. It works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes. It can also be used against certain species of Leishmania protozoa which are a type of unicellular parasites that also contain ergosterol in their cell membranes. In addition to its antifungal and antiparasitic actions, it also has some antibacterialproperties. It is marketed in various formulations under various brand names.

Miconazole is also used in Ektachrome film developing in the final rinse of the Kodak E-6 process and similar Fuji CR-56 process, replacing formaldehydeFuji Hunt also includes miconazole as a final rinse additive in their formulation of the C-41RA rapid access color negative developing process.
It is on the World Health Organization’s List of Essential Medicines, the most important medications needed in a basic health system.[1]

ALTERNATIVE ROUTES beginning with the racemic raw material will likely be more costly or more time-consuming to develop, Cox says. Crystallization might be tricky because the stereogenic center does not have a group that can readily undergo acid-base chemistry. Catalytic asymmetric chemistry will necessitate converting the raw material to an appropriate substrate and identifying effective, as well as usable, chemical catalysts or biocatalysts.
What happens to the unwanted enantiomer also depends on the economics. Reracemizing and feeding the racemate back into the process is ideal but not always practical. In the miconazole case, the raw material costs $32 per kg. It is unlikely that reracemizing would be less costly in this example, Cox explains.
People should not forget that the goal of chiral technologies–enantiopure product–also may be achieved with chemistry that already exists, notes David R. Dodds, founder of Dodds & Associates LLC, Manlius, N.Y., a consulting service for biotechnology and chemical companies. Process chemists seek the most robust, most productive, and least expensive synthetic route and aim to find it as fast as possible. Any reaction that can help reach this goal is useful. It is the overall process cost that will dictate which reactions will be used. And that cost covers not only reagents but also waste streams, utilities, equipment use, unit operations, and downstream requirements. Thus, it may be more commercially attractive to replace an elegant but expensive single reaction with several more mundane ones that have a lower total cost, he says. Such a situation is likely to arise when an asymmetric step requires an expensive chiral catalyst or chiral auxiliary.

Miconazole nitrate was prepared by Godefori et
al
[5­
7]. Imidazole 1 was coupled with
brominated 2,4‑dichloroacetophenone 2 and the resulting ketonic product 3
was reduced with sodium borohydride to its corresponding alcohol 4. The
latter compound 4 was then coupled with 2,4-dichlorotoluene by sodium borohydride
in hexamethylphosphoramide (an aprotic solvent) which was then extracted with
nitric acid to give miconazole nitrate.

 

 

2-     Miconazole was also
prepared by Molina Caprile [8] as follows:
Phenyl methyl ketone 1 was brominated to give
1-phenyl-2-bromoethanone 2. Compound 2 was treated with
methylsulfonic acid to yield the corresponding methylsulfonate 3.
Etherification of 3 gave the a‑benzyloxy derivative 4 and compound 4 was
then chlorinated to give the 2,4‑dichlorinated derivative in both aromatic ring
systems 5. Compound 5 reacted with imidazole in dimethylformamide
to give miconazole 6 [7] which is converted to miconazole nitrate.

 

3-     Ye
et al reported that the reduction of 2,4-dichlorophenyl-2-chloroethanone
1 with potassium borohydride in dimethylformamide to give 90% a‑chloromethyl-2,4-dichlorobenzyl
alcohol 2. Alkylation of imidazole with compound 2 in dimethyl­formamide
in the presence of sodium hydroxide and triethylbenzyl ammonium chloride, gave
1-(2,4‑dichlorophenyl-2-imidazolyl)ethanol 3 and etherification of 3
with 2,4-dichlorobenzyl chloride under the same condition, 62% yield of
miconazole [9].
4-     Liao
and Li enantioselectively synthesized and studied the antifungal activity of
optically active miconazole and econazole. The key step was the
enantioselective reduction of 2‑chloro-1-(2,4-dichlorophenyl)ethanone catalyzed
by chiral oxazaborolidine [10].
5-     Yanez
et al reported the synthesiz of miconazole and analogs through a
carbenoid intermediate. The process involves the intermolecular insertion of
carbenoid species to imidazole from a‑diazoketones with copper acetylacetonate as the key
reaction of the synthetic route [11].
