Reference of 497-25-6, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2. In a Patent£¬once mentioned of 497-25-6
A and tin ycin A fully synthetic method (by machine translation)
The invention relates to a and tin ycin A fully synthetic method, the method consists in the compound (S)- 3 – ((S)- 1 – amino – 3 – methyl-butyl) – 8 – hydroxy isoflavone chroman – 1 – one with compound (2S, 3S, 4S) – 2 – amino – 4 – (benzyloxycarbonyl amino) – 6 – (uncle butoxy) – 3 – ((tert-butyl dimethyl) oxy) – 6 – oxo caproic acid by condensation reaction to obtain the key intermediate (3S, 4S, 5S) – 5 – azido – 3 – (benzyloxycarbonyl amino) – 4 – hydroxy – 6 – ((1 – (8 – hydroxy – 1 – isoindole chroman – 3 – yl) – 3 – methyl-butyl) amino) – 6 – butyl oxo caproic acid uncle; and then sequentially through the hydrogenation reduction, the cyclization reaction, takes off uncle butyl dimethyl silicon ether reaction, hydrolysis reaction to obtain ohwada ycin A. The method of the invention with the raw materials are easy, simple operation, low cost and the like, the resulting product ohwada cephalosporin A has broad spectrum bacterial inhibiting activity and anti-tumor activity.
