Methyl 2-(2,2,4-trimethyl-6-tosyl-perhydro-1,3-dioxino[5,4-c]pyridin-5-yl)acetate.

Acta crystallographica. Section E, Structure reports online

Selvanayagam S, Sridhar B, Ravikumar K, Kathiravan S, Raghunathan R.
PMID: 21583906
Acta Crystallogr Sect E Struct Rep Online. 2009 Apr 22;65:o1091. doi: 10.1107/S1600536809014391.

The title compound, C(20)H(29)NO(6)S, crystallizes with two mol-ecules in the asymmetric unit, with similar conformations. The dioxane and pyridine rings adopt twist conformations in both mol-ecules. The packing is stabilized by inter-molecular C-H⋯O hydrogen bonds.

1-Vinyl-1H-indole-3-carbaldehyde.

Acta Crystallogr Sect E Struct Rep Online. 2008 May 30;64:o1163. doi: 10.1107/S160053680801547X.

In the title compound, C(11)H(9)NO, the C and O atoms of the attached carbaldehyde group deviate by just 0.052 (2) and 0.076 (1) Å, respectively, from the mean plane of the indole ring system. In addition to van der...

Role of cadaveric dissections in modern medical curricula: a study on student perceptions.

Anatomy & cell biology

Dissabandara LO, Nirthanan SN, Khoo TK, Tedman R.
PMID: 26417481
Anat Cell Biol. 2015 Sep;48(3):205-12. doi: 10.5115/acb.2015.48.3.205. Epub 2015 Sep 22.

The shift from traditional medical curricula to newer teaching and learning approaches such as problem-based learning has often resulted in omission or significant reduction of cadaveric dissections as a method of learning anatomy. The objective of this study was...

(1,2,3,4-Tetra-hydro-isoquinoline-2-carbo-dithio-ato-κS,S')(thio-cyanato-κN)(tri-phenyl-phosphane)nickel(II).

Acta crystallographica. Section E, Structure reports online

The Ni(II) atom in the mononuclear title compound, [Ni(C(10)H(10)NS(2))(NCS)(C(18)H(15)P)], exists within a S(2)PN donor set that defines a distorted square-planar geometry. A significant asymmetry in the Ni-S bond lengths support the less effective trans effect of SCN(-) over PPh(3).
