Myristic aldehyde

He found present in the oil myristic aldehyde, i-lcrpincol, and a sesquiieipene. 

Both isomers yield myristic aldehyde on oxidation by means of potassium permanganate. This aldehyde has the formula... 

With propnonic aldehyde, butyraldehyde, valeraldehyde, cenanthol, myristic aldehyde, nitrobenzaldehyde, phenylacetaldehyde, furfurol, and others, the reaction can be carried out. All the compounds obtained contain the methyl groups of the two acetacetic ester molecules, but the third side-chain is different, depending upon the nature of the aldehyde employed.

Esters constituted the largest family and included acetates (ethyl, propyl, isobutyl, butyl, isoamyl, and phenethyl), ethyl esters of fatty acids (propanoate, isobutanoate, butanoate, hexanoate, octanoate, 3-hydroxybutanoate, 3-hydroxyhexanoate and furcate), ethyl esters of organic acids (pyruvate, lactate, ethyl myristate, diethyl malate and, mono- and diethyl succinate) and various other esters, such as methyl butanoate, isobutyl lactate and phenylethyl octanoate. The acids quantified included isobutanoic, butanoic, hexanoic, octanoic, decanoic, lauiic and 3-methylbutanoic. The lactones included y-butyrolactone, pantolactone, y-decalactone and E- and Z-oak lactone and the terpenes included neral d-terpineol, P-dtronellol and Z-nerolidol. The aldehyde family comprised acetaldehyde, benzaldehyde, furfural, 5-methylfurfural and octanal, and the phenol family included eugenol, 4-ethylphenol and 4-ethylguaiacol. Finally, 1,1-diethoxyethane, acetoin, sotolon, 2, 3-butanedione, p-cymene and methionol were also determined. 

Certain saturated and unsaturated compounds migrate together in TLC on layers which have been rendered hydrophobic this is as found in other partition procedures such as liquid-liqtdd counter-current distribution and partition chromatography in columns or on impregnated paper. Thus, as seen from Fig. 148, methyl palmitate (C g, saturated) and methyl oleate (C g, monoolefine) appear together in one spot as do methyl myristate (Cj4, saturated) and methyl linoleate (Cjg, diolefine). Such critical pairs are likewise formed by the corresponding free acids or aldehydes and also by tripalmitin/triolein and trimyristin/trilinolein [78]. 

Saturated fatty acids, such as myristic, palmitic, and stearic acid, have been used as the carboxylic acid component of vinyl esters [56]. In the hydroformylation with a heterogeneous Rh/C catalyst, mainly the branched aldehyde was observed, which in turn was converted into the corresponding alcohols (Scheme 6.97).

Here again, brevetoxin B2 was isolated from a New Zealand mollusk, the greenshell mussel Perm canaliculus. Brevetoxins B3 are appreciably different from the previously mentioned brevetoxins insofar as it concerns a mixture of two esters a palmitate and a myristate of the same cyclic polyether. These two compotmds, which occur in equal quantities in the mixture, were isolated from the mussel Pema camliculus, and would have come from a transformation of brevetoxin B the opening of cycle D esterification of the alcohol obtained and oxidation of the terminal aldehyde into acid by the mollusk (Morohashi et al., 1995). 

An essential feature of bacterial bioluminescence is the requirement for long chain aldehyde (p. 156). Some bacteria, or certain mutants thereof, can use long-chain fatty acids, especially myristic acid [107] as precursors of the aldehydes. Thus a dark mutant of B. harveyi emits light when myristic acid is added. The light yield is proportional to the quantity of the acid added, down to 10 picomoles per ml.
