In the preparation of this report, the Venice Commission has relied on the comments of its rapporteurs; its recently adopted Report on Respect for Democracy, Human Rights and the Rule

To sum up, by means of a simple method, in a single step at room temperature based on the high insolubility in the reaction medium of the PCs 1 and 2, we can control the

In the previous sections we have shown how astronomical alignments and solar hierophanies – with a common interest in the solstices − were substantiated in the

The organic phase was washed with saturated aqueous solutions of NaHCO 3 and NaCl, dried over Na 2 SO 4 , and the solvent was removed under reduced pressure to obtain the

To a solution of this diastereomeric mixture (31.19 mmol) in acetone at 273 K was added the O-Ethylxanthic acid potassium salt (46.78 mmol) and the reaction was stirred at

Synthesis of Bicycloprolines and Related Derivatives by 1,3-Dipolar Cycloaddition of Azomethine Ylides.

The reaction mixture was diluted with AcOEt (50 mL) and washed with water (3 × 50 mL), dried (Na 2 SO 4 ) and concentrated in vacuo and the crude mixture was purificated by

The organic layer was separated, dried with MgSO 4 , the solvent evaporated to dryness and the residue purified by column chromatography (SiO 2 : DCM). The solvent
