Solution properties of cellulose tris(3,5‐dimethyl‐phenylcarbamate)
Macromolecular Symposia, 1997AbstractThe dilute‐solution behavior and liquid crystal formation of cellulose tris(3,5‐dimethylphenylcarbamate) (CTDC) in 1‐methyl‐2‐pyrrolidone (NMP) at 25°C are discussed by summarizing our recent studies, and its molecular characteristics are compared with those of cellulose tris(phenylcarbamate) (CTC) in the same solvent.

The rearrangement of glycicyl N‐phenylcarbamate
Journal of Heterocyclic Chemistry, 1970AbstractThe thermal rearrangement of glycicyl N‐phenylcarbamate yields 3‐phenyl‐4‐hydroxymethyl‐2‐oxazolidone and not 3‐phenyl‐5‐hydroxytetrahydro‐1,3‐oxazin‐2‐one as reported previously.

[Derivatives of phenylcarbamic acid as potential antituberculotics].
Ceska a Slovenska farmacie : casopis Ceske farmaceuticke spolecnosti a Slovenske farmaceuticke spolecnosti, 2012Basic esters of phenylcarbamic acid were studied by the teams of Prof. Cizmárik and Prof. Waisser as potential antituberculotics. Their antimycobacterial activity increased with lipophilicity. The most active derivatives were substituted with an alkoxy group in position p- on the phenyl.

[Acute toxicity of two phenylcarbamates: propham and chloropropham].
Comptes rendus des seances de la Societe de biologie et de ses filiales, 1982The bibliographic data dealing with the acute toxicity of two phenylcarbamates, propham and chloropropham, are not very precise an often contradictory. This work is a restatement and also a demonstration of the high sensitivity of the aquatic animals that we have tested (Amphibia and Crustacea) in comparison with the Mammals (rat and mouse).

A new single-stage method for obtaining of betulin phenylcarbamates
Journal of Asian Natural Products Research, 2017A new single-stage synthesis of betulin phenylcarbamates is suggested that uses 1-phenylurea as a reagent for betulin O-carbamoylation. A chemoselectivity of hydroxyl-groups in carbamoylation of betulin with 1-phenylurea appeared to occur. Synthesized nitrogen-containing betulin derivatives - phenylcarbamates are valuable as bioactive substances.

Skelettumlagerungen unter Elektronenbeschuß–VII: Alkyl‐N‐Phenylcarbamate
Organic Mass Spectrometry, 1973AbstractDie Massenspektren einfacher Alkyl‐N‐Phenylcarbamate werden beschrieben, Die bekannte Skelettumlagerung, die beim Aethyl‐N‐phenylcarbamat zu einem [C6H5NHCH2]+‐Ion2 führt, wird auch bei den Methyl‐, Propyl‐ und Butylhomologen beobachtet.

Quantum‐Chemical Study of Phenylcarbamates with Local Anesthetic Activity
Archiv der Pharmazie, 1984AbstractThe quantum‐chemical PCILO method has been used to perform a conformational analysis of the 1‐[2‐(2‐methoxyphenylcarbamoyloxy)ethyl]piperidine (B) and its cation (BH⊕) which belong to a group of phenylcarbamates with considerable local anesthetic activity. For B the most stable conformation has a gauche arrangement of the O‐C‐C‐N fragment.
