摘要:
Four different optical isomers of a new compound, 1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol are now provided as new substances. These four optical isomers are now named as (2R, 1'S)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, (2S, 1'S)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, (2S, 1'R)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, and (2R, 1'R)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanol, respectively. These four optical isomers have different activities for their .beta.-adrenergic-blocking effect and .alpha.-adrenergic-blocking effect and are useful as valuable agents for therapeutic treatment of various cardiovascular diseases, as compared to an optically inactive racemic mixture of said isomer compounds. These four optical isomers may be produced and isolated from each other by chromatographing (1'S)- or (1'R)-N-[2'-(o-methoxyphenoxy)-1'-methylethyl]-5-(4"-isocarbostyriloxymethyl)-2-oxazolidones to isolate either its (5R, 1'S)-isomer and its (5S, 1'S)-isomer, or its (5S, 1'R)-isomer and its (5R, 1'R)-isomer therefrom separately and then hydrolyzing each of these isolated isomers under alkaline conditions to obtain separately (2R, 1'S)-, (2S, 1'S)-, (2S, 1'R)- and (2R, 1'R)-1-[2'-(o-methoxyphenoxy)-1'-methylethylamino]-3-(4"-isocarbostyriloxy)-2-propanols.
摘要:
An Al-killed cold-rolled steel sheet with excellent demagnetization characteristics is provided which is substantially consisted of 0.005% or less C; from 0.05 to 0.50% Mn; 0.010% or less S; from 0.01 to 0.08% Sol.Al; 0.0050% or less N; wherein Mn %/S %.gtoreq.7 and (Sol.Al % - 0.003%)/N %.gtoreq.6; and the remainder iron and inevitable impurities. A shadow mask made of such Al-killed cold-rolled steel sheet and a color television receiver using the same exhibit a very excellent function. A preferred process for producing such an Al-killed cold-rolled steel is also provided, said process being characterized in first obtaining a steel or a specific composition by the use of a vacuum degassing apparatus and then subjecting the steel to sequential steps of hot rolling, cold rolling, decarburization-annealing, and cold rolling.
