γ-Lactam analogues of monocyclic β-lactam antibiotics, the oxamazins, have been prepared from N-protected γ-nitro-α-amino acid esters. Unlike the oxamazins, these higher homologues are devoid of biological activity.

The reactions of α,ω-dihaloalkanes with one equivalent of thiourea have been investigated. Certain ω-chloro-α-iodoalkanes give satisfactory yields of ω-chloroalkylisothiouronium iodides which on hydrolysis directly afford cyclic sulfides.
