Abstract
A compound of the formula ##STR1## in which: R.sup.1' is hydrogen or a carboxy-protecting group; PA1 R.sup.41' is hydrogen or a hydroxy-protecting group; PA1 R.sup.42' is a C.sub.1 -C.sub.6 alkyl, a C.sub.1 -C.sub.6 alkoxy, a halogen, an aryl or an aryloxy; R.sup.43' is hydrogen, a C.sub.1 -C.sub.6 alkyl, a C.sub.1 -C.sub.6 alkoxy, a hydroxy, a halogen, a cyano, a nitro or a group of the formula --NR.sup.8' R.sup.9', where R.sup.8' and R.sup.9' are independently selected from the group consisting of hydrogen, amino-protecting groups, C.sub.1 -C.sub.6 alkyl groups and phenyl groups, or R.sup.8' and R.sup.9' together represent a group --(CH.sub.2).sub.q '--O.sub.r '--(CH.sub.2).sub.s '--, where q' and s' are independently 0 or an integer of from 1 to 5 and r' is 0 or 1, provided that (q'+s') is an integer of at least 2; R.sup.45' and R.sup.46' are independently selected from the group consisting of C.sub.1 -C.sub.6 alkyl groups and aryl groups, or R.sup.45' and R.sup.46' together represent a group --(CH.sub.2).sub.q '--O.sub.r '--(CH.sub.2).sub.s '--, where q' and s' are independently 0 or an integer of from 1 to 5 and r' is 0 or 1; Y' is oxygen or sulfur; and j' is 0, 1 or 2.
