This effect depends significantly on the polarity of the solvents and the nature of the ylide. Key Words: Stereochemical control; Wittig olefination.
During the course of our efforts to synthesize natural products constituents of Bryophytes, we needed to prepare different stilbenes and thus, we made extensive use of olefination reactions.
The simplicity 270 Boden model 110 high yields that are usually obtained when performing the Boden modifica- tion of the Wittig reaction potassium bases and crown-6 as the ylide- forming reagent were appealing to us. Also, the mildness of this procedure makes it suitable for use on complex substrates, such as those in our synth- esis of marchantinquinone, a natural quinone from Bryophytes.
The Wittig reaction has enjoyed widespread application in synthetic chemistry and, aside from its 270 Boden model 110 use, it morel also mechanistically interesting, bringing about problems of stereoselectivity. Much work has been conducted in order to achieve control over the either cis- or trans-olefin formation, not always sharing the same viewpoints and conclusions. items Discover our range of dresses for women at Boden.

There are two limiting geome- tries for the cyclic transition state: the cis-selective state containing a puckered oxaphosphetane, which minimizes 1,3 omdel interactions, and the trans-selective state containing a planar ring, which minimizes 1,2 steric interactions between the carbonyl substituent and the one on the ylide carbon, Sch.
