Reaction of 1-pentanol with propionic acid provides 1-pentyl propionate [624-54-4] a new coatings solvent for automotive refinish and OEM paints, apphances, and for higher-solids systems (37). The esterification of 1-pentanol with formic acid to 1-pentyl formate [638-49-3] is conducted by concomitant removal of by-product water by a2eotropic distillation with diethyl ether (38).

Because anti/syn ratios in the product can be correlated to the E(0)/Z(0) ratio of the involved boron enolate mixture,10b initial experiments were aimed at the preparation of highly E(0)-enriched boron enolate. The E(0)/Z(0) ratio increases with the bulk of the alkanethiol moiety, whereas the formation of Z(O) enolates prevails with (S )-aryl thioates. (E/Z = 7 93 for benzenethiol and 5 95 for 2-naphthalene thiol esters). E(O) reagent can be formed almost exclusively by reaction of (5)-3,3-diethyl-3-pentyl propanethioate 64 with the chiral boron triflate. High reactivity toward aldehydes can be retained in spite of the apparent steric demand (Scheme 3-22).43... 

Shu and co-workers (35) identified 2-isobutyl-3,5-diisopropylpyridine, 2-pentyl-3,5-dimethylpyridine, and its dihydro derivative obtained under similar conditions. Sultan (29) confirmed the presence of 3,5-diethyl-2-propylpyridine in a model system consisting of butyraldehyde and ammonium sulfide. Our proposed mechanism of their formation (20) consists of three steps 1) aldol condensation of the starting aldehydes to 2,4-alkadienals, 2) imine formation with ammonia, and 3) subsequent cyclization and oxidation to corresponding pyridines. An alternate mechanism, suggested by Shu and co-workers (33), takes into consideration the isolated dihydro derivatives. Hwang and co-workers described another dihydro derivative (19, R = Bu, R = R" = Pr, R= H) (37). 

Pentyl-5 ( 2 ) -carbomethoxyoctyl-2-cyclopentenone and 2(5)-Hexyl-5 (2)-carbomethoxyheptyl-2-cyclopentenone (4). These cyclic ketones constitute about 35% (estimated by GLC) of the neutral diethyl ether extract of the salts and amount to 4.6% of the final reaction mixture of carboxylated linoleate. Analyses by GLC (JXR column) show one peak of retention time of 1.06 relative to that of 1 TLC (silica gel G, diethyl ether-petroleum ether, 1 3) Rf 3.74 compared with 5.04 for 2 IR (neat) 1740 (ester C=0), 1700 and 1630 cm"1 (C=C—C=0) UV max... 

Chiral allenylboronic esters.1 The enantioselectivity in synthesis of homo-propargylic esters by the reaction of aldehydes with chiral allenylboronic esters (11, 181) is markedly increased by use of bis-2,4-dimethyl-3-pentyl esters of d- or vAaxtaric acid rather than the diethyl ester. Yields in the reaction of various saturated aldehydes are 70-90%, and optical yields are consistently greater than 90% and even higher (97-99%) when the aldehyde is present in excess. However, yields are poor in reactions with aryl and a,p-unsaturated aldehydes. This modified procedure was used in a synthesis of (S)-(—)-ipsenol (2) from d-(—)-bis(2,4-di-methyl-3-pentyl) tartrate (1) (equation I).

A comparison of diethyl amide 107, 3-pentyl ketone 108, 3-pentyl ether 109, and alcohol 110 was conducted in order to examine the effects of the side-chain conformation on both potency and selectivity in the carboxamide series of inhibitors (Fig. 14).100 The ketone, ether, and alcohol resembled the amide in that all showed selective inhibitory activity towards influenza A NA. An sp2-hybridized center was found to contribute to the potency of 107 and 108. 

Suzuki et al. [Ill] screened three solvents—methylene chloride, diethyl ether, and benzene—to determine their ability to produce optimum elution of phthalic acid monoesters sorbed on a styrene divinylbenzene polymer (Figure 2.40). The effect of elution solvent strength on the recovery of the free acid form of the monomethyl (MMP), ethyl (MEP), -propyl (MPRP), K-butyl (MBP), K-pentyl (MPEP), and -octyl (MOP) phthalates is compared. The phthalic acid monoesters are arranged in Figure 2.40 in the order of increasing number of carbons in the alkyl chain, which in turn is roughly correlated with an increase in hydrophobicity. 

An amount of 1.20 mg (0.9 mmol) of pentyl carboxylate-functionalized SWCNTs (Scheme 1.23) was mixed with 150 mg (0.9 mmol) of 4,5-benzo-l,2-oxathiin-2-oxide in 40 mL of ODCB and the mixture was irradiated in a focused microwave reactor at 150 W for 45 min. The ODCB was removed by vacuum distillation and the residue was purified by washing several times with pentane and diethyl ether to obtain benzobutenylene-functionalized SWCNT as a dark-brown solid [171]. 

Equimolar quantities of tellurium tetrachloride and 3,3-bis[chloromercuro]-2,4-pentanedione in refluxing 1,4-dioxane produced 3-(chloromercuro)-2,4-dioxo-3-pentyl tellurium trichloride. The brown solid (recrystallized from diethyl ether) retained two molecules of dioxane that are slowly given off on storage9. 

The various titanium mixed systems have been used not only to reduce dinitrogen to ammonia, but also to hydrazine (55) and to organonitrogen compounds. Thus, mixtures of TiCL, sodium, and naphthalene were found to give traces of naphthylamines (55). Reaction of (17-C5H5)2Ti(CsH5)2 with phenyllithium in the presence of N2 gave small amounts of aniline (55). Reaction of (rj-CjHs TiCU with Mg, N2, and diethyl ketone afforded a mixture of 3-pentylamine and di(3-pentyl)amine in 25-50% yield based on fixed N2 (56).

As early as 1891 Claisen noted that isoxazoles, when treated with sodium and either pentyl alcohol or moist diethyl ether, undergo reductive ring opening to give 1,3-enaminoketones. These products may then be hydrolyzed to 1,3-dicarbonyl compounds. In more recent times the use of readily available isoxazoles as masked 1,3-dicarbonyl compounds has found wide application in synthesis, although dissolving...
