摘要:A compound represented by the formula ##STR1## wherein R 1 represents a lower alkyl group or a lower haloalkyl group; R 2 represents a lower alkyl group, a lower haloalkyl group, an aralkyl group, or a group of the formula --COOR 4 or --SO 2 R 5 in which R 4 represents an aralkyl group or a substituted or unsubstituted alkyl group and R 5 represents an alkyl group or a substituted or unsubstituted aryl group; and R 3 represents a hydrogen atom or a carboxyl protecting group which can be easily split off. This compound is useful in the production of a 6-(disubstituted amino)carbapenem-series antibiotic. n The compounds of the formula ##STR2## wherein R 1 and R 2 are as defined above are important intermediates for the synthesis of the compounds of formula (I) and/or the aforesaid di-(substituted amino) carbapenem-series antibiotics.

摘要:The method and materials of this invention make possible substantially faster techniques for organic-aqueous extractions and routine chemical reactions work-ups. The inventive material uses silicone elastomer-coated glass powders, magnetic powders, and sponges as absorbents to extract organic products from an aqueous mixture. After separation from the mixture, these different forms now loaded with organic products can serve as a convenient input for flash chromatographic separations or other processing. With these techniques, tedious liquid-liquid extractions are replaced by a simple solid filtration or transfer and emulsion formation is eliminated. These versatile sorbents can also be used for larger scale work-ups, various extractions of organics from an aqueous solution (e.g., water purification) or gas phase and various analytical or other applications.
