Strategy opportunistic

Opportunistic strategies. These are usually found by chance. For an example, see the route from compound 5 to compound 6 actually chosen by Woodward et al. m. 

The strategy for boundary crossing has been implemented however, by the addition of the hexane another critical feature has been created. Hexane must be regenerated, but it is in a different distillation region than the only remaining unprocessed stream (Ml). In this case the possible boundary crossing strategic operations are Mixer 6 and Decanter 7. Two opportunistic distillations. Fractionators 8 and 9, can also be appHed to Ml (decantation is also a possible opportunistic separation).

In less repetitive syntheses, it is possible to use remote functional groups as "control elements", a technique which depends more upon the opportunist tactics developed in the course of a synthesis rather than of a premeditated strategy. Such is the case, for instance, of the synthesis of strychnine (i) by Woodward [2], in which after synthesising the intermediate 2 a hydrogen at C(8) must be introduced onto the P-face (4), i.e., onto the most hindered concave face of the molecule (Scheme 8.1). Usually the reduction with a metal hydride would lead to the a-C(8)-H isomer (i.e., the hydride ion will atack from the less hindered face of the molecule), however in the present case the P-OH group at C(21) acts as a control element and, besides the reduction of the amide at C(20), a hydride ion attacks at C(8) from the P-face by an intramolecular transfer of the complex C(21)-0-Al-H (3). 

Designing haptens in order to stimulate the production of catalytic antibodies depends on a variety of strategies based on transition state analogs, entropy traps and opportunistic chemistry. 

In the face of the difficulties in finding children and young people who would talk about these aspects of their lives, the research strategy to sample purposively, across the birth order and equally between genders etc, had to adapt to the reality that the sample would be opportunistic. In the event, the most likely child to be interviewed was the eldest, and more females than males agreed to be interviewed (20 16). It was most likely that they would be older in years too. Partly this was because younger children (8-10 years)...

The treatment of patients with AIDS and individuals infected by HIV is continually being modified as new drugs become available and more information is gained about the nature of the AIDS virus. Currently, the pharmacologic management of HIV-infected patients consists of two principal strategies (1) controlling the proliferation and effects of HIV in individuals infected with this virus and (2) treatment and prevention of various opportunistic infections that... 

The only division in CDER with an established policy regarding pre-IND consultation meetings is the Division of Anti-Viral Drug Products (DAVDP). Established in 1988, the DAVDP pre-IND Consultation Program is a proactive strategy designed to facilitate informal early communications between DAVDP and potential sponsors of new therapeutics for the treatment of AIDS and life-threatening opportunistic infections, other viral infections, and soft tissue trans-...
