权利人:SANRAKU INC
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 present invention provides methodology for carbon-nitrogen bond formation via vinyl or aryl amination. In the process of the invention, an sp 2 hybridized radical is reacted with an azomethine moiety to form pyrrolidine and indole compounds. The methodology provides a facile process for the synthesis of compounds having the pyrrolidine or indole subunit and is especially advantageous for compounds having acid or base labile functional groups and/or is comprised of chiral centers susceptible to acid/base epimerization.
