On treatment of lr,3c-diacetoxy-2t-nitrocyclohexane (3) or its 1,3-dimesyloxy analogue 4 with primary amines or ammonia, nitrodiamines (5–11) are obtained via an elimination-addition mechanism. Similar aminations of lr-methyl-1-nitrocyclohexane-2c,6c-diol (15) or its di-O-acetate 16 give C-methyl branched nitrodiamines (12–14), which are also formed by reaction of glutaraldehyde with nitromethane and amines. Structures and conformations of the products obtained were deduced from IR and NMR data.
