dl‐Seryl‐dl‐Alanyl‐Glycyl‐Glycyl‐dl‐Alanyl‐Glycin und dl‐Alanyl‐Glycyl‐Glycyl‐dl‐Seryl‐dl‐Alanyl‐Glycin

Justus Liebigs Annalen der Chemie, 1958
Abstract1) Aus Carbobenzoxy‐Dl‐seryl‐Dl‐alanyl‐glycin‐azid und Glycyl‐Dl‐alanyl‐glycin‐benzylester wurden die Carbobenzoxy‐hexapeptid‐benzylester synthetisiert und durch fraktionierte Kristallisation nach katalytischer Hydrierung die vier Racemate A, B, C und D von Dl‐alanyl‐glycyl‐glycyl‐Dl‐alanyl‐glycin erhalten.—2) Zwei Racemate A und B des ...

Total Synthesis of Indole and Dihydroindole Alkaloids. VI. The total synthesis of some monomeric vinca alkaloids: dl‐Vincadine, dl‐vincaminoreine, dl‐vincaminorine, dl‐vincadifformine, dl‐minovine and dl‐vincaminoridine

Helvetica Chimica Acta, 1975
AbstractA synthetic approach to a variety of monomeric Vinca alkaloids is described. The sequence involves, among its crucial phases, the generation of appropriate nine‐membered ring intermediates which are then elaborated via a transannular cyclization approach to the desired natural products.

A simple, stereospecific synthesis of DL-muscarine and DL-allomuscarine

Tetrahedron Letters, 1968
Abstract A bromolactone (VII) was stereospecifically converted to a tetrabydrofuran (IVa, Me/CO2H cis) and a dimethylamide (VIII, Me/CONMe2 trans. Possible mechanisms for these reactions are discussed. Since IVa and VIII have been transformed to dl -muscarine (I) and dl -allomuscarine (II) respectively, stereospecific formation of IVa and VIII ...

POLYMORPHISM OF THE DL-A SYSTEM

Transplantation, 1972
SUMMARY The major histocompatibility system of the dog (DL-A) was studied in more detail by immunogenetical methods. Suggestive evidence for the existence of two closely linked DL-A (sub)loci was found. The definition of three alleles at the first sublocus was clear for both mongrel and beagle populations.

XPath for DL Ontologies

Proceedings of the AAAI Conference on Artificial Intelligence, 2015
Applications of description logics (DLs) such as ontology-based data access (OBDA) require understanding of how to pose database queries over DL knowledge bases. While there have been many studies regarding traditional relational query formalisms such as conjunctive queries and their extensions, little attention has been paid to graph ...

SPARQL-DL: SPARQL Query for OWL-DL.

2007
There are many query languages (QLs) that can be used to query RDF and OWL ontologies but neither type is satisfactory for querying OWL-DL ontologies. RDF-based QLs (RDQL, SeRQL, SPARQL) are harder to give a semantics w.r.t. OWL-DL and are more powerful than what OWL-DL reasoners can provide.
