Ethyl 2',5'-dichloro-4'-thiocyanatofumaranilate. Pelosi, Stanford S., Jr. (Morton-Norwich Products, Inc., USA). U. 26367-48-6 and 772-12-3 are cas registry numbers. These chemicals are also mentioned in this article.S. US 4002659 11 Jan 1977, 2 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07C161-02. NCL: 260454000. APPLICATION: US 76-649584 16 Jan 1976. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) Section cross-reference(s): 5 (E)-I was prepd. by treatment of 2,5,4-Cl2(NCS)C6H2NH2 (II) with Et fumaroyl chloride (III) in acetone contg. K2CO3. (E)-I has antibacterial activity (no data). For example, a 60% yield of (E)-I was obtained by refluxing for 5 h approx. equimolar amts. of II and III in acetone contg. K2CO3 and then allowing to stand overnight. .

Can an aromatic ring alter the reactions of a nearby unsaturated imide? A study of the rate and selectivity of nitrile oxide cycloaddition reactions of acryloyl derivatives of the Rebek imide benzoxazole

Can an aromatic ring alter the reactions of a nearby unsaturated imide? A study of the rate and selectivity of nitrile oxide cycloaddition reactions of acryloyl derivatives of the Rebek imide benzoxazole. Curran, Dennis P.; Yoon, Moon-Hwan (Dep. of Chemistry, Univ. of Pittsburgh, Pittsburgh, PA 15260, USA). Tetrahedron, 53(6), 1971-1982 (English) 1997 Elsevier.Several reagents such as 188106-62-9 is used here. CODEN: TETRAB. ISSN: 0040-4020. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Cycloaddns. of acryloyl derivs. of the Rebek imide benzoxazole (I; R = acryloyl, methacryloyl, crotonoyl, cinnamoyl, fumaroyl, 2,4-pentadienoyl) are extraordinarily stereoselective, but have rates and regioselectivities that otherwise parallel those of a simple achiral model. It appears that the benzoxazole rings of these compds. completely shields the inner face of the nearby alkene, but has no measurable effect on the rate of reactions on the outer face. .
