Heptyl methyl ether

This type of coordination is useful for highly stereoselective syntheses of cyclopropane derivatives. Reaction of A -cyclohexenyl methyl ether with the Simmons-Smith reagent gives CM-2-bicyclo[4.1.0]heptyl methyl ether without the trans isomer 103). The Simmons-Smith reaction with 7-tCT f-hutoxynorbornadiene gives syn-exo- IV) and syn-endo isomer (V) without the anti isomers 260). 

Unsymmetrical ethers may be produced from the acid-promoted reactions of aldehydes and organosilicon hydrides when alcohols are introduced into the reaction medium (Eq. 173).327,328 An orthoester can be used in place of the alcohol in this transformation.327 335 A cyclic version of this conversion is reported.336 Treatment of a mixture of benzaldehyde and a 10 mol% excess of triethylsilane with methanol and sulfuric, trifluoroacetic, or trichloroacetic acid produces benzyl methyl ether in 85-87% yields.328 Changing the alcohol to ethanol, 1-propanol, 2-propanol, or 1-heptanol gives the corresponding unsymmetrical benzyl alkyl ethers in 45-87% yield with little or no side products.328 A notable exception is the tertiary alcohol 2-methyl-2-propanol, which requires 24 hours.328 1-Heptanal gives an 87% yield of //-lie ply I methyl ether with added methanol and a 49% yield of benzyl n-heptyl ether with added benzyl alcohol under similar conditions.328...

Ether cleavage of 4-heptyl-3-methylveratrole 121 using boron tribromide affords 4-heptyl-3-methylcatechol 122 (Scheme 38). Oxidation of the catechol 122 with o-chloranil to 4-heptyl-3-methyl-l,2-benzoquinone 123 and subsequent immediate addition of aniline leads to 5-anilino-4-heptyl-3-methyl-l,2-benzo-quinone 124. Unlike the very labile disubstituted ort/zo-quinone 123, compound 124 is stable and can be isolated. Palladium(II)-mediated oxidative cyclization of the anilino-l,2-benzoquinone 124 provides carbazoquinocin C 51.

Mix 230 ml of dry ethanol with 32.5 g of sodium methoxide under a nitrogen atmosphere until the methoxide is dissolved. Add 110 g of diethyl malonate and stir for 10 min, then add 75 g of 3-nonene-2-one (or equimolar amount of 5,6-dimethylundec-3-ene-2-one for dimethyl-heptyl) keeping the temp below 49° with external cooling. Stir and reflux for 3 hours, cool to room temp, neutralize with coned HCL add (about 45 ml), and let stand for 8-12 hours. Evaporate in vacuo, and dissolve the residue in 1 N HCl acid and 800 ml ethylacetate. Allow to stand to separate the ethyl acetate, then wash it (the acetate) with two 300 ml portions of water and extract with a saturated solution of NaHCOs until a small sample shows no turbidity upon acidification (it will take at least nine 100 ml portion extractions). Combine the NaHCOs extractions and very carefully acidify them with tiny portions of acid. Extract with three 300 ml portions of ether, and remove the ether by evaporation in vacuo after drying with MgS04 to get the methyl-carboxylate.

HoUow-fiber SLMs have been used in the removal of phenol from aqueous matrices. Kujawski et al. [142, 143] studied polypropylene membranes impregnated with methyl-terbutyl ether, cumene, and/or a mixture of hydrocarbons. With Cyanex 923 (a mixture of trialkylphosphine oxides), the recoveries of phenol reached of 98% into the stripping phase from the 0.2 mol.dm solution of caustic soda [144, 145]. Carriers for phenol removal from wastewaters have included hnear monoalkyl cyclohexane [146], N,N-di(l-methyl heptyl) acetamide [147], dibenzo-18-crown-6 [148], dodecane [149], trioctylamine [150], and N-octanoylpyr-rolidine [151]. Many diluents and carriers are of synthetic origin, and so their application carries with issues of flammabUity, volatility, toxicity, and potential detrimental effects to the environment and the health of the human population [152]. 

CM-2,6-dialkyl-2//,6/f-l,3,5-oxaselenazines (237) are synthesized from selenoamides, aldehydes (236 R = methyl, heptyl, or t-butyl), and boron trifluoride etherate (Equation (56)) <90CL913>.

In this reaction, too, the stability of the alkyl radical being eliminated influences the ease of fragmentation. The order of ease of elimination based on results from the two studies cited above is t-butyl> isopropyl > benzyl > ethyl >chloromethyl> methyl l-bicyclo[2.2.1]heptyl. Radicals derived from ethers and acetate are also subject to fragmentation, with elimination of a ketone or ester ... 

Free radical additions to alkenylboronic esters provided the first access to (a-haloalkyl)boronic esters [8]. Intramolecular cyclizations involving radical additions to alkenylboronic esters have been reported and, also, a (l-iodo-S-hexenyl)boronic ester cyclizes to the cyclopentyl derivative under radical conditions [83]. Reaction of pina-col (l-iodopentyl)boronate with tributyltin hydride and butyl vinyl ether yielded the addition product pinacol (l-butoxy-3-heptyl)boronate (71%), but addition of the bory-lalkyl radical to methyl acrylate was inefficient and yielded mainly the simple reduction product, pinacol pentylboronate [84].
