    摘要: The present invention provides a method by which a 6-hydroxyethyl penam compound represented by General Formula (2) below can be produced with a high selectivity:

    wherein R represents a hydrogen atom or a protective group for carboxylic acid and X 2 represents a halogen atom;
    the method including the steps of reacting a Grignard reagent with a halogeno penam compound represented by General Formula (1) below:

    wherein R and X 2 are the same as above, and X 1 represents a halogen atom;
    reacting the generated compound with an amine compound; and
    further reacting the generated compound with acetaldehyde.

    摘要: A process for the preparation of a penam derivative of formula (I):
    wherein R A is hydrogen or a group of formula (la):
    wherein X is -C0 2 R', or S0 3 R'; R is C 1-6 alkyl, aryl, or heterocyclyl; R' is hydrogen, or a pharmaceutically acceptable salt-forming ion or ester-forming radical, and R 2 represents hydrogen or a pharmaceutically acceptable salt-forming ion or in vivo hydrolysable ester-forming radical; which process comprises reacting a compound of formula (II):
    wherein R B is hydrogen, a removable amino blocking group, or a group of formula (Ila):
    wherein Y is -CO 2 R x or -SO 3 R x ; R is as defined with respect to formula (I) above; R x represents an ester-forming radical, R y represents hydrogen, a salt-forming radical or a carboxyl-blocking group, and R 3 represents an alkyl, benzyl, or aryl group; with methanol in the presence of copper ions; and thereafter if necessary carrying out one or more of the following steps:

    (i) removal of any blocking group;
    (ii) converting the product to a pharmaceutically acceptable salt or ester thereof.
