摘要:
AbstractTrimethylene sulfite, m.p. − 14°, crystallizes in the orthorhombic system, space group P212121, Z = 4. The unit cell dimensions at − 100° are a = 7.451, b = 7.703 and c = 8.98 Å. The structure was solved by means of a Patterson synthesis and refined by the least squares method, using three‐dimensional reflexion data (MoKaradiation, collected at − 100°). The six‐membered ring has the chair conformation and the SO bond points toward the axial direction. The geometry of the ring is described in terms of t

摘要:
AbstractTransalkylation reactions between germanium derivatives, including substituted digermanes, have been investigated. These reactions, which usually need a catalyst,e.g.a germanium dihalide, are tentatively explained by an electrophilic attack on the carbon atom of a germanium‐carbon bond of the alkyl‐donor. Many reactions reported in the literature which involve alkyl‐transfer among derivatives of the IVB group elements can be interpreted in the sam

摘要:
AbstractThe enzyme specificity in the biosynthesis of prostaglandins has been investigated by incubation of a particulate fraction of sheep vesicular glands with ω6 tri‐ and tetraenoic C18‐ C22fatty acids and isomers of ω6 eicosatrienoic acid (20: 3 ω6). The chemical synthesis of the various substrate fatty acids is described. The tetraenoic fatty acids were converted into a series of prostaglandin E2homologues and the trienoic fatty acids into a series of prostaglandin E1homologues. The only isomer of 20: 3 ω6 which showed a fairly high conversion into an isoprostaglandin E1was the ω7 compound. Maximum conversions were obtained from ω6 C20acids.The smooth muscle stimulating activity of prostaglandin E1and E2appears to be very specific. All other prostaglandins had much lower a

摘要:
AbstractPrimary alcohols related to prostaglandins were prepared by reduction of the methyl ester of prostaglandin E1with lithium tetrahydridoaluminate. The structures of the reaction products were established by mass spectrometry.
