چکیده
In the molecule of the title compound, C(18)H(32)N(2)O(4), the central bicyclo-[3.3.0]octane (octa-hydro-penta-lene) has a rigid ring junction. Both rings of the bicyclo-[3.3.0]octane unit adopt an envelope conformation, and the flexible tert-butyl-carbamoyl side chains each have an extended conformation. Such a constrained bicyclo-[3.3.0]octane aliphatic template is of inter-est with respect to the design of novel self-assembling motifs. Mol-ecules related by c-glide symmetry are linked via inter-molecular N-H⋯O hydrogen bonds, forming a two-dimensional layer structure. Neighboring layers are weakly associated along the a axis due to the close approach of the tert-butyl-carbamoyl groups (2.55 Å).

متن کاملEfficient microwave assisted syntheses of 2,5-diketopiperazines in aqueous media.
Aqueous in situ one-pot N-Boc-deprotection-cyclization of N alpha-Boc-dipeptidyl-tert-butyl and methyl esters under microwave irradiation afforded 2,5-diketopiperazines (DKPs) in excellent yields. This protocol is rapid, safe, environmentally friendly, and highly efficient, and showed that the tert-butoxy moiety is also an excellent leaving group for these cyclizations.
