Strategies construction

Overall, each of these dendrimer construction strategies offers advantage and disadvantages. Some of these issues, together with experimental laboratory procedures, are viewed in more detail in several of the following chapters.

A formal constructability VIP workshop conducted in the conceptual phase (FEL-I) should focus on the overall project construction strategies regarding site layout, construction and turnaround laydown areas, access to the site for large equipment and modules, modularization, sequencing of heavy lifts, limitations regarding procurement, limitations regarding fabrication and transport, area labor limitations, and coordination with any existing or nearby structures or facilities.

There is a growing interest in polymers with architectures that differ from the classical linear polymers, since new polymer architectures may exhibit unusual behavior. For example, the combination of dendrimers and linears polymers in hybrid materials has evolved from a curiosity into an important trend in current chemistry. Therefore, various dendrimer construction strategies have been developed on the basis of classical organic and inorganic chemistry [65,66],... 

In a similar heterocyclic quinodimethane ring construction strategy, the hexacyclic adducts (64) were isolated in good yield upon condensation of appropriately functionalized indole imines with ( )-bicyclo[2.2.1]hept-5-ene-2-carboxylic acid chloride (Equation (35)) (88JA2242). In a demonstration of the utility of this new method for indole alkaloid synthesis, further transformations conducted on compound (64 R = R2 = H, R3 = Et) were shown to lead to ( —)-16-methoxy-tabersonine. 

Initially, the Z matrix was utilized simply as a means of geometry input. It was subsequently found that optimization was generally more efficient in Z-matrix coordinates than in Cartesians, especially for acyclic systems. This is not always the case, and care must be taken in constmcting a suitable Z matrix. A short discussion on good Z-matrix construction strategy is given by Schlegel [39]. 

Figure 6.30 shows the application of the algorithm to the structure of strychnine. This leads to an interesting proposed ring construction strategy as shown in Figure 6.31.
