The ethyl urethane of aziridine was attacked by the carbazole anion gen-ernated using sodium to give 32 lithium hydride in xylene provided the means for the preparation of 29 (R = 33 and R = 34) from the corresponding bromides. ... [Pg.98]

Pyrrolidines piperidines.7 Reaction with benzeneselenenyl chloride converts A4-and As-unsaturatcd ethyl urethanes into phcnylseleno-substituted pyrrolidines and piperidines, respectively. Yields are considerably improved by the presence of silica gel, which presumably facilitates the ring closure subsequent to addition of the reagent to the double bond (equation I). [Pg.18]

URETHANE. [CAS 51-79-6], CO(NH2)OC2H5, also referred to as ethyl carbamate or ethyl urethane. Its structure is typical of the repeating unit in polyurethane resins. Colorless crystals or white powder, odorless, saltpeterlike taste. D 0.9862. mp 49C, bp 180C solutions neutral to litmus, soluble in w ater, alcohol, ether, glycerol, and chloroform slightly soluble in olive oil. Formed by the heating of ethanol and urea nitrate to 120-130% or by the action of ammonia on ehtyl carbonate or ethyl chloroformate. [Pg.1653]

They also described the reaction of diketene with N,N-dimethylurea in acetic acid, yielding 50 (see also Ahmed et a/.177). Gunar et a/.178 used diketene in the reaction with cyanic acid (see also Ozaki179), thiocyanic acid, ethyl urethane, and N,N -disubstituted ureas in acetic acid medium to obtain 50. When a 2-thiono derivative was obtained from thiocyanic acid, as in Eq. (37), they desulfurized it with mercuric acetate. [Pg.24]

The Curtius reaction of l,2,5-thiadiazole-3-carbohydrazide (79) proceeded normally and in high yield to the ethyl urethane (80, R = Et). The ethyl urethane, however, resisted acid hydrolysis and was extensively decomposed by base. The benzyl urethane (80, R = CH2Ph), on the other hand, was smoothly hydrolyzed to the amine with aqueous acid. Attempts to prepare 1,2,5-thiadiazole-3,4-dicarboxazide from the dihydrazide resulted in an unstable product which exploded violently. ... [Pg.135]

Kobashi, K. (1992) Urease activity of /fe/Zcobacterpytor/. /. Clin. Pathol.. 45.367-368. Urechollne " bethanechol chloride, urethane inn (ethyl carbamate ethyl aminoformate ethyl urethane NSC 746) was formerly used clinically as a HYPNOTIC, and can be used as a GENERAL ANAESTHETIC in small animals. It has been used as an anticanCER agent in treating chronic myeloid leukaemia. [Pg.285]

Perhydropyrido[l,2-c]pyrimidine-l,3-diones were prepared in the reaction of alkyl 2-piperidineacetate with ethyl urethane in diethyl ether in the presence of sodium (56CB1642), by heating with KOCN in hydrochloric acid (59CB637 64JMC146). l-Thioxoperhydropyrido[l,2-c] pyrimidin-3-one was obtained when ethyl 2-piperidine acetate was reacted with KSCN in acidified ethanol (59CB637). Reaction of methyl 2-piperidyl acetate with aryl isocyanates yielded 2-arylperhydropyrido[l,2-c]pyrimidine-... [Pg.67]

If such addition reactions can be carried out cleanly in high yields, di- and polyisocyanates might be made from ethylenediacrylate, A(A -methylenebis(acrylamide), an unsaturated polyester made from maleic anhydride. However, it would be desirable to find a noncarcinogenic analogue of the ethyl urethane, preferably one for which the adduct... [Pg.36]
