Water Scarcity in the Mediterranean: Perspectives Under Global Change
Water shortage impacts hydrologic assets, platforms connectivity, biodiversity, water caliber, and river environment functioning. It has direct affects on fiscal sectors that use and depend upon water, akin to agriculture, tourism, undefined, strength and delivery. The Mediterranean Basin is without doubt one of the areas on the planet such a lot liable to weather alterations, in addition to some of the most impacted by way of human water call for.

In Rodrigo's synthesis of the lignans of Podophyllum,all eight diastereomers could be obtained from the common intermediate 227 [193]. 1] nucleus of 227, Eq. 139. Pelter's synthesis of (-)-isopodophyllotoxin utilized a similar hydrogenolysis strategy with an asymmetric Diels-Alder oxabicyclic adduct derived from menthol (Menth) as substrate, Eq.

Because the majority of these compounds are derived from oxyallyl cation cycloadditions, most experiments on the three-carbon bridge involve addition to the bicyclic ketone. 1] ketone 90 undergoes reduction with bulky hydride sources such as L-selectride to generate the endo alcohol, Eq. 68 [112]. Presumably, the selectivity is due to equatorial attack of the hydride at the ketone of the pyranone in a pseudo chair conformation.
