Pivalolactone, 1 interchange reactions with polypivalolactone [PDF]

open access: yes, 1993
Ester interchange, alcoholysis, and acidolysis of polypivalolactone (PPVL) were studied by melting PPVL with bisphenol diacetates, 1, 4-butanediol, or aromatic diacids.

Chromosomal location of a gene that controls sterol esterification in Triticum aestivum L. [PDF]

open access: yes, 1974
A previously described D genome locus (Pln) that controls sterol esterification in the wheat kernel has been assigned to the short arm of chromosome 7 D by comparison of the steryl ester phenotype of euploid kernels of Triticum aestivum variety Chinese ...

Highly Diastereo- and Enantioselective Allylboration of Aldehydes using alpha-Substituted Allyl/Crotyl Pinacol Boronic Esters via in Situ Generated Borinic Esters [PDF]

open access: yes, 2013
Readily available, alpha-substituted allyl/crotyl pinacol boronic esters often give low E/Z selectivity (with Z favored) in reactions with aldehydes. We found that addition of nBuLi to the pinacol boronic ester followed by trapping of the alkoxide with ...

Structure, Conformation and Contact Analyses of Six Aromatic Diamide Diesters

open access: yesCrystals, 2023
Six meta-substituted isophthalamide diesters (DxE) and pyridinedicarboxamides (PxE) are reported with spectroscopic and crystal structure analyses (D = meta-C6H4; P = meta-pyridine; xE = 2-/3-/4-ethyl ester substitution). Comparisons are made between the

L_1-distance for additive processes with time-homogeneous L\'evy measures [PDF]

open access: yes, 2014
We give an explicit bound for the $L_1$-distance between two additive processes of local characteristics $(f_j(\cdot),\sigma^2(\cdot),\nu_j)$, $j = 1,2$. The cases $\sigma =0$ and $\sigma > 0$ are both treated.

Stigmasterol-Based Novel Low Molecular Weight/Mass Organic Gelators

open access: yesMolecules, 2011
Conjugates consisting of stigmasterol and L-phenylalanine, interconnected through short-chained dicarboxylic acyls by ester and amide bonds, respectively, were synthesized as potential low molecular weight/mass organic gelators (LMWGs/LMMGs).
