Despite the fact that the [2 + 2] -photocycloaddition reaction of enones has a history of more than 100 years, it has remained a vital and attractive reaction. The continuing interest and many applications to increasingly more complex targets not only bear testimony to its utility but also contradict the myth that photochemical reactions are nonselective and unpredictable. It would be desirable if this most useful chemistry could also be appreciated in the life sciences industry. The first blockbuster drug to be synthesized via a [2 + 2]-photocycloaddition is yet to be developed. Apart from the conventional evolution of the reaction, which involves an increase in scope and an improvement in its practical execution [154], it is expected that sensitization - as a means of catalyzing photochemical reactions in general [155-157] - will become a dominant factor in the development of catalytic enantioselective [2 + 2]-photo-cycloaddition variants. [Pg.205]

Freud thus comes down squarely on the side of the true believers in the myth of masturbatqi mental illness. I must confess that here again I am unable to share Stekel s point of view.. .. As he sees it, the injuriousness of masturbation amounts to no more than a senseless prejudice which, purely as a result of personal limitations, we are unwilling to cast off with sufficient thoroughness. I believe, however, that. .. to take up such a position contradicts our fun-... [Pg.196]

I have heard or read a number of psychology-related statements from motivational speakers and consultants that sound like good common sense but in fact contradict scientific knowledge. Some of these statements appear so many times in the pop psychology literature that they are accepted as basic truths, when in fact they cannot be substantiated with objective evidence. Consider, for example, the following 15 myths which are commonly stated but make no sense. [Pg.11]

This myth is of course inconsistent with the prior myth that managers should spend more time with less productive employees. My refutation of Myth 9 leads to an obvious contradiction of this myth. Specifically, managers should play favorites. As 1 indicated previously, managers need to spend more time with their more talented employees. [Pg.15]
