摘要： A novel three-step process for preparing 4-(3,4-dichlorophenyl)-4-phenylbutanoic acid is disclosed, which involves (1) reducing 4-(3,4-dichlorophenyl)-4-ketobutanoic acid to 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid; (2) then converting the intermediate hydroxy acid formed in the first step to 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone, and (3) thereafter reacting the resulting gamma-butyrolactone compound with benzene in a Friedel-Crafts type reaction to form the desired final product. The latter compound is known to be useful as an intermediate leading to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone and ultimately, to cis-(1S)(4S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalene amine (sertraline), which is known to be a preferred anti-depressant agent in the field of medicinal chemistry. The aforementioned 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone and 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid are both novel compounds. There is also disclosed a novel process for converting 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone directly to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone, as well as an alternate novel process for converting 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid directly to this same key intermediate.

摘要： A lightweight ready-mix concrete composition that contains 8-20 volume percent cement, 11-50 volume percent sand, 10-31 volume percent prepuff particles, 9-40 volume percent coarse aggregate, and 10-22 volume percent water, where the sum of components used does not exceed 100 volume percent. The prepuff particles have an average particle diameter of from 0.2 mm to 8 mm, a bulk density of from 0.02 g/cc to 0.64 g/cc, an aspect ratio of from 1 to 3. The slump value of the composition measured according to ASTM C 143 is from 2 to 8 inches. After the lightweight ready-mix concrete composition is set for 28 days, it has a compressive strength of at least 1400 psi as tested according to ASTM C39.
