Poly(polyhedral)s: synthesis and study of a new class of polyurethanes composed of homocubanes

“…The basketane diester 9 and diol 10 were rearranged to the corresponding snoutane derivatives ( 14 and 15 , respectively) in excellent yields using silver nitrate . NMR and IR spectra recorded for compounds 15 and 16 were consistent with the data reported in the literature . Compounds 14 , 17 and 18 constituted new compounds and were characterized using 1 H and 13 C NMR spectroscopy, FTIR spectroscopy, elemental analysis and mass spectrometry.…”

“…Homocubanes, such as basketane and snoutane, also feature polyhedral structures yet have been underutilized in polymeric materials . Due to their relatively low symmetries and compact structures, we hypothesized that the integration of these cage‐like compounds into the backbones of polymeric materials should enhance their intrinsic physical properties while retaining high solubility.…”

Syntheses and rearrangements of cage molecules related to cubane

“…(XXI) (LV) (CXXXVIII) " onstrated that the silver catalysis of 1,8-bishomocubane to the snoutane derivatives passes by way of a cyclopropylcarbinyl cation (23). Similar studies have been carried out with homocubane derivatives (24), and the action of transition metals, in particular rhodium(I) and palladium(II) complexes, on bishomo and homocubane derivatives has also been investigated (25).…”

Design and synthesis of novel bis-annulated caged polycycles via ring-closing metathesis: pushpakenediol

“…Several intricate targets ( Fig. 1 ), such as snoutane ( 1 ) [ 18 ], basketane ( 2 ) [ 19 ], tetrahedrane ( 3 ) [ 20 ], triprismane [ 21 ], rocketene ( 4 ) [ 22 ], cubane ( 5 ) [ 23 ], garudane ( 6 ) [ 24 ], dodecahedrane ( 7 ) [ 25 – 26 ] and golcondane ( 8 ) [ 27 ] were assembled by employing various novel synthetic routes.…”
