(United States of America). CODEN: USXXAM. CLASS: IC: C07C047-20. NCL: 260601000R. APPLICATION: US 68-742178 3 Jul 1968. DOCUMENT TYPE: Patent CA Section: 30 (Terpenoids) Section cross-reference(s): 17 (EtO)2CHCH2CH2CMe:CHCH2CH2C(:CH2)CH:CH2 (I), obtained by Wittig reaction of CH2:CHC(:CH2)CH2CH2CHO with (EtO)2CHCH2CH2CMe:PPh3 or of (EtO)2CHCH2CH2COMe with CH2:CHC(:CH2)CH2CH2CH:PPh3 was sepd. into its cis and trans isomers, which were hydrolyzed and the cis and trans aldehydes treated with CHCMe:PPh3 to give the flavoring materials cis- and trans-.beta.-sinensal [CH2:CHC(:CH2)CH2CH2CHCMe:CHCH2CH:CMeCHO], resp. Thus, cis- and trans-I, obtained from CH2:CHC(:CH2)CH2CH2CHO and (EtO)2CHCH2CH2CMe:PPh3 and sepd. 6139-84-0 and 26926-69-2 are also in the experiment. chromatog., were refluxed with OCHCMe:PPh3 in benzene contg. H2SO4 for 2 hr to give cis- and trans-CH2:CHC(:CH2)CH2CH2CH:CMeCH2CH2CHO, which were refluxed in benzene for 40 hr to give cis- and trans-.beta.-sinensal, resp. Trans,trans,trans-EtO2CCMe:CHCH2CH2CMe:CHCH2CH:CMeEt was prepd. similarly from ICH2CH2CH:CMeCH:CH2 and EtO2CCMe:CHCH2CH2COMe. .

Tetrahydrofuryluracils: Tetrahydrofuryluracils. Kobayashi, Yukinari; Sone, Takanori; Takagi, Seiji; Sako, Kiyohide; Himeno, Itsuo (Asahi Chemical Industry Co., Ltd., Japan). Japan. Kokai JP 52108984 12 Sep 1977 Showa, 4 pp.Some commonly used reagents like 6139-84-0 is used in this experiment. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07D405-04. APPLICATION: JP 76-23123 5 Mar 1976. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 27 I (R = H, halo, Me, trihalomethyl; R1 = trialkylsilyl, trialkylstannyl) were treated with R2(CH2)3CHO (R2 = halo) to give II. II are virucides and antitumor agents (no data). Thus, 27.4 g I (R = F, R1 = Me3Si) and 12.8 g Cl(CH2)3CHO in MeCN were refluxed 5 h at 90° to give 68% II (R = F). .
