5-(1H-Inden-2-yl)-1,3-benzodioxole [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 In the title compound, C(16)H(12)O(2), the non-H atoms are coplanar with a mean r.m.s. deviation of 0.0260 (2) Å. The deviations of the bond angles from normal values at the indenyl junction C atom and the indenyl bridgehead C atom nearest the junction are imposed by the five-membered ring geometry.

6-Hydroxy-2H-1,3-benzodioxole-5-carbaldehyde [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 The title compound, C(8)H(6)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. The benzodioxole ring system is almost planar in each mol-ecule, with maximum deviations of 0.008 (1) and 0.007 (1) Å. The mol-ecular structure is characterized by strong electrostatic intra-molecular O⋯O contacts [2.649 (3) Å] and intra-molecular O-H⋯

Acta Crystallographica Section E Structure Reports Online, 2007 The title compound, C7H4O3, is the first cyclic carbonate of an aromatic diol whose structure has been elucidated by means of single-crystal X-ray analysis. The molecule possesses crystallographic twofold rotation symmetry and non-crystallographic C2v symmetry. The C—O single bonds are slightly longer than those in comparable cyclic carbonates derived

Investigation into the bioisosteric approach in the design, synthesis and evaluation of muscarinic receptor ligands [PDF]
, 2013 The acetylcholine (ACh) receptor system belongs to rhodopsin GPCR family and is an integral membrane protein divided into two types: muscarinic and nicotinic. The naturally occurring neurotransmitter acetylcholine binds to these two receptor systems non-

1-(1,3-Benzodioxol-5-yl)pentan-1-one [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 In the mol-ecule of title compound, C(12)H(14)O(3), the benzodioxole ring system is essentially planar. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains along the c axis, and π-π contacts between dioxole rings and between dioxole and benzene rings of the benzodioxole ring systems [centroid-centroid ...

1,2-Bis[(1,3-benzodioxol-5-yl)methylidene]hydrazine [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 The complete mol-ecule of the title compound, C(16)H(12)N(2)O(4), is generated by the application of a centre of inversion. The (1,3-benzodioxol-5-yl)methyl-idene fused-ring system is approximately planar (r.m.s. deviation = 0.020 Å) and is essentially coplanar with the central hydrazine group [dihedral angle = 5.08 (9)°].

Farnesol-Like Endogenous Sesquiterpenoids in Vertebrates: The Probable but Overlooked Functional ?Inbrome? Anti-Aging Counterpart of Juvenile Hormone of Insects? [PDF]
, 2015 Literature on the question whether the juvenile stage of vertebrates is hormonally regulated is scarce. It seems to be intuitively assumed that this stage of development is automated, and does not require any specific hormone(s).
