Chirality-directed self-assembling of long-chain dialkyl 3,7-diazabicyclo[3.3.1]nonane-2,6-dione-1,5-dicarboxylates
Abstract
Dihexyl and didodecyl 3,7-diazabicyclo[3.3.1]nonane-2,6-dione-1,5-dicarboxylates 4a,b were synthesised, and the self-assembling of the molecules of strictly alternating configurations was observed in a crystal of bis-lactam 4b, which resulted in formation of H-bonded heterochiral
