Abstract: 3-[(Alkoxy)(aryl or heteroaryl)methyl]-1H-indoles which are useful as color formers in pressure-sensitive carbonless duplicating systems and thermal marking systems are prepared by reacting 3-[(arylsulfonyl)(aryl or heteroaryl)methyl]-1H-indoles with alcohols in the presence of a base.
Abstract: The S-acylation of a mercaptoacyl amino acid having ACE inhibitory action with a diuretic containing a carboxyl group yields a product having both ACE inhibitory action and diuretic activity in vivo.
Abstract: Biochemical optical resolution of DL-tryptophanes in which DL-tryptophane amides are interacted with the culture products, or their treated products, of a microorganism capable of producing amidase is described. L-tryptophane amides in racemic DL-tryptophane amides are asymmetrically hydrolyzed to form optically active L-tryptophanes at a high yield and almost all D-tryptophane amides remain without being subjected to hydrolysis. The resultant D-tryptophane amides are readily hydrolyzed, after separating L-tryptophanes, to form optically active D-tryptophanes at a high yield.

Abstract: 1,2,4-Triazolo[4,3-c]pyrimidines substituted at the 5 or 7 position through a nitrogen atom which is part of a heterocyclic ring have been found to have potent bronchodilator activity and to be useful synthetic intermediates in the preparation of 1,2,4-triazolo[1,5-c]-pyrimidines. Methods for inducing bronchodilation, pharmaceutical compositions, and synthetic processes and intermediates are also described.
Abstract: Triaminotriarylmethane colorants are obtainable by first reacting an aluminum or iron trihalide complex of a 4,4',4"-trihalotriphenylmethyl halide with a metanilic acid, a sulfanilic acid or a .beta.-naphthylaminesulfonic acid and then reacting the product with one or more anilines to replace the halogen atoms located in the 4-positions.The compounds according to the invention are very useful as pigments, for example in printing inks, or for toning carbon black.

Abstract: A coproduct continuous dealkylation process is described in which 4-t-butoxy-n-butanol is contacted with acidic silica-alumina catalyst at temperatures in the 160.degree.-200.degree. C. range (reactor wall temperature) in the liquid hourly space velocity regime of 2:0 to 6:0 liter/liter catalyst/hr. to produce in a single reactor a mixture in which the ultimate product of conversion of the 4-t-butoxy-n-butanol is 1,4-butanediol (1,4-diol) and tetrahydrofuran (THF) present in a preselected ratio (mole %) of 1,4-diol to THF ranging from 7:3 to 3:7. The 1,4-diol produced is useful in the preparation of polyesters, e.g. polybutylene terephthalates, and THF is a useful intermediate in the manufacture of certain chemicals and plastics.

Abstract: 3,4,5-Trithiatricyclo[5.2.1.0.sup.2,6 ]decanes and derivatives are prepared in high yield by contacting a bicyclo[2.2.1]hept-2-ene compound and sulfur in the presence of a solvent, and a catalytic amount of sulfide ions.
Abstract: Preparation process of indole from aniline and ethylene glycol. Upon preparing indole by reacting aniline and ethylene glycol in a gas phase and in the presence of a catalyst, ethylene glycol is charged in portions to a multiplicity of catalyst stages formed by dividing a catalyst bed and connected in series. This divided supply of ethylene glycol permits the suppresing of the decomposition of ethylene glycol, even if the molar ratio of feed aniline to total feed ethylene glycol is small. The above process permits making the yield of indole large and reducing the amount of unreacted aniline to be separated and recovered from the reaction effluent.
Abstract: Indole, and/or methyl-substituted indoles are described as prepared from the corresponding 2-(cyanomethyl)cyclohexanone starting material through a catalytic reaction in the presence of hydrogen, using a metal, or metal compound, of Group VIII or Group Ib of the Periodic Table. The reaction is carried out at an elevated temperature at high conversion to yield the corresponding indole and (in some cases) tetra- or hexahydroindoles.
