Derivations of Onsager’s Reciprocal Relations
The Journal of Chemical Physics, 1954Two derivations of Onsager's reciprocal relations are presented in simplified form, and the range of their validity is discussed.

On binary operators and their derived relations
BIT, 1988Considering a list of abstract binary operations and relations, the author gives a sequence of seven simple to prove, but interesting and very useful theorems, which appear frequently in algebra and other fields. All results are known, but the approach is nice and appropriate for teaching, with a good generality.

Selenotyrosine and related phenylalanine derivatives
Bioorganic & Medicinal Chemistry, 2001A new series of Se-substituted phenylalanine derivatives has been synthesized having the para position of the phenyl ring substituted by selenocyanate (-SeCN), seleninic acid (-SeO(2)H), or selenol (-SeH) functional groups. The starting material for synthesis was 4'-aminophenylalanine, which is readily available in DL- or L- forms.

The Derivation of Syntactic Relations
1998Abstract Alongside explicit specifications of “syntactic feature” and “permissible syntactic feature bundle” (i.e., a possible syntactic category), perhaps the most fundamental construct postulated within syntactic theory is that of a “syntactic relation.” For example, the following are each considered to be core syntactic relations. a.

There are many parallels between homomorphisms and derivations. Having just about any result on homomorphisms, one may ask whether a similar result, possibly under milder assumptions, is true for derivations. It is therefore not surprising that some of the results on homomorphisms from the preceding chapter have their counterparts for derivations. This

Silipramine and related derivatives
Journal of Organometallic Chemistry, 1978A series of new 10,11-dihydro-5H-dibenzo[b,f]silepins are prepared from the reaction o,o′-dilithiobibenzyl with the chlorosilanes HSiCl3, ClCH2CH2CH2SiCl3, MeSiHCl2 and MeSi(CH2CH2CH2Br)Cl2. The only isolated silepin product produced from HSiCl3 is the spiro derivative.

Peptide derivatives of tylosin-related macrolides
Russian Journal of Bioorganic Chemistry, 2007Approaches to the synthesis of model compounds based on the tylosin-related macrolides desmycosin and O-mycaminosyltylonolide were developed using specially designed peptide derivatives of macrolide antibiotics to study the conformation and topography of the nascent peptide chain in the ribosome tunnel.

A Tyrosine-Derived Benzofuranone Related to Diazonamide A
Organic Letters, 2000[formula: see text] Cyclization of 8 with PPA followed by MCPBA oxidation affords the benzofuranone 10. Treatment with a chiral chloroformate in the presence of DMAP affords the target benzofuranone 13 via an enol ester 12.
