Cyclobutane-derived diamines: synthesis and molecular structure.
Cyclobutane diamines (i.e., cis- and trans-1,3-diaminocyclobutane, 6-amino-3-azaspiro[3.3]heptane, and 3,6-diaminospiro[3.3]heptane) are considered as promising sterically constrained diamine building blocks for drug discovery. An approach to the syntheses of their Boc-monoprotected derivatives has been developed aimed at the preparation of multigram amounts of the compounds. These novel synthe...
متن کاملSyntheses of C2-symmetric vicinal diamines derived from tartaric acid
C2-symmetric vicinal diamines 3b–f, derived from L-tartaric acid, with increasingly bulky terminal ether functionalities were prepared using two distinct sequences. Diamines 3b,c were obtained from the corresponding vicinal diols 4b,c, while diamines 3d–f were generated from dihydroxydiazide 7 via deprotection–reprotection strategies. © 1999 Elsevier Science Ltd.

متن کاملDerived Photosensitive Pigments from Invertebrate Eyes
The red pigment in the eyes of the squid, blue crab, and horseshoe crab becomes photosensitive when treated with formalin, and bleaches in the light. The resulting change in density is approximately symmetrical around a maximum at 480 mmicro in the blue green. This difference absorption spectrum is in rough agreement with the spectral sensitivity of the cephalopod eye and differs only slightly ...
متن کاملSupramolecular Electronics Derived from Porphyrin-like Pigments
The field of organic based electronics has become a blossoming area of intensive study during the past decade. The promise of a cheaper and easier-to-process alternative to inorganic based semiconductor materials makes these materials highly desirable. Additionally, organic based electronics can be made into flexible structures, allowing for the fabrication of visual displays that can be folded...
متن کاملMultiple deprotonation of primary aromatic diamines by LiAlH4.
Reaction of LiAlH4 with 1,2-phenylenediamine (1H4) in THF results in formation of the metallocyclic amido-/imido complex [{Al(1H2)}2{Al(1H)2}2][Li(THF)2]4 (3), while in the presence of various Lewis base ligands 1,8-diaminonaphthalene (2H4) gives the amido-('ate') complexes [Al(2H2)2](-)[Li(LL')](+) [L = THF, L' = PMDETA (N,N,N',N',N''-pentamethyldiethylenetriamine) (4); L = L' = TMEDA (N,N,N',...
