    摘要: A novel intermediate for synthesizing 1 .beta.-alkyl-1-carbapenem, i.e., 4 .beta.-(1 .beta.-alkyl-2-carboxyprop-2-enyl)azetidin-2-one (II), is prepared stereoselectively by treating 4-(leaving group substituted)azetidin-2-one (I) with trans-2-(leaving group substituted)-methyl-3-alkylacrylic acid (III) and a reducing metal. ##STR1## wherein R.sup.1 is hydrogen, alkyl, or substituted alkyl;R.sup.2 is optionally substituted alkyl;R.sup.3 is hydrogen or a carboxy-protecting group; andR.sup.4 and R.sup.5 each is a leaving group.

    摘要: A novel process is disclosed for converting known 3,4-disubstituted azetidinones to carbapenems. The process proceeds through novel N-substituted intermediates and then cyclizes to the 4-position of the azetidinone to form the carbapenem.

    摘要: Disclosed is a chiral, total synthesis of thienamycin from D-glucose which proceeds via intermediates I, II and III to known aldehyde IV which is known to be useful in the total synthesis of thienamycin (V): ##STR1## wherein: R is lower alkyl having 1-6 carbon atoms or bi-valent alkyl having 2-6 carbon atoms which joins the two sulfur atoms; R.sup.1 is lower alkyl or aralkyl, such as benzyl and the like; and R.sup.2 is hydrogen or a removable protecting group, such as triorganosilyl wherein the organo groups are independently selected from lower alkyl, phenyl and phenylloweralkyl.
