Supported initiator

Communications should be two-way, incorporating mechanisms (e.g., questionnaires, response cards, callback numbers, etc.) for soliciting feedback from the people receiving information. This is particularly true of communications that support initiatives like PSM that require cooperation and may require changes in working habits. 

The overall process from amino ketone 36 to Efavirenz (1) required four steps with an overall yield of 72% and quite high purity of the isolated 1, as described above. This process supported initial marketing of Efavirenz but there were a few drawbacks. The key asymmetric addition of acetylide required 2equiv of precious cyclopropylacetylene (37). In addition, two steps out of the total four steps were protection with pMB and its deprotection. 

The high-mileage supported initiators previously mentioned involve a species similar to XX as part of a mixed titanium-magnesium-chloride lattice, usually involving Mg—Cl—Ti bonds. Ti and Mg are interchangeable within the metal lattice. 

Various methods have heen studied for obtaining supported metallocenes, with silica, (Si02) , as the most-used support material [Fink et al., 2000, 2001 Hlatky, 2000 Kaminsky, 2001 Tannous and Soares, 2002]. The methods differ in the sequence used for reaction of support, initiator, and coinitiator. The coinitiator first method is the most commonly used method. Silica is treated with MAO or with TMA followed by water to fix MAO on silica. The metallocene initiator is then added to produce the supported metallocenium species... 

Detailed studies by L abbe et al. support initial formation of 4-alkyl-5-iminothiatriazoles by addition of the azide to the C=S of the isothiocyanate. The thiatriazoline then undergoes the type of transformations outlined in Scheme 13. Tetrazoline (95) is also formed as a minor product by addition of the azide to the N=C of the isothiocyanate <75JHC607,77JOC1159>, see also <75CC24>.

The A piperideine trimer hypothesis is supported initially by the equal incorporation of lysine and cadaverine into all three alkaloid fragments13,14 but more significantly by the incorporation of three molecules of A piperideine (1) into lupanine (10) and by the manner of this incorporation label from C-6 appeared at C-2, C-15, and, by inference, C-10, whereas C-2 label appeared at C-17, C-ll, and, by inference, C-6, consistent with the hypothesis (see Scheme 3).19 Further, approximately a third of the label was located at each of the determined sites. 

The overall changes in the transformation of the supported precursor to the supported active oxide should obviously be understood. The supported initial precursor and the supported final oxide each correspond to one of the types of supported phase-support interactions described in Figs 3-9. It is very important to identify changes from one picture to another during calcination. The general tendency will be to reach higher thermodynamic stability through ...
