Hoy establishes a basis for a naturalistic political theory that can be sustained as a continuity from Aristotle through the Enlightenment and post-Enlightenment contributions of David Hume, John Dewey, Evolutionary Biology, and Deep Ecology.
This entails several contentions. First he argues that the contemporary relevance of Aristotelian naturalism can be defended within the context of a pragmatic realism without recourse to a no-longer-tenable metaphysical biology. Second, he calls for an emphasis on a historicized nature-the human capacities for language, sociality, and habituation that are the product of biological-cultural interaction in human evolution. Third, Hoy contends that, while humans are perceived as the apex of other forms of life, a compassionate relation of humans to non-human nature is a logical extension of human community and moral obligation. His final contention is that an integrative framework for a naturalistic political theory can be formulated within the theoretical categories contributed by John Dewey. Scholars and students of political theory, philosophy, evolutionary biology, and deep ecology in particular will find this study of interest.
Dipolar cycloaddition chemistry has found many useful synthetic applications, particularly with respect to the preparation of compounds with new chiral centers. This approach toward asymmetric syntheses is of major importance in both the pharmaceutical and agricultural industries. Synthetic Applications of 1,3-Dipolar Cycloaddition Chemistry Toward Heterocycles and Natural Products provides a comprehensive, current reference for the synthesis of complex molecules based on cycloaddition reactions. Updating Albert Padwa’s popular 1984 volume, this new edition shifts the text’s focus from theory, structure, reactivities, and selectivities to synthetic applications. Both carbonyl ylides and nitronates, important members of the 1,3-dipole family that were not reviewed previously, are now included. <p> Beyond the ability of the 1,3-dipolar cycloaddition reaction to produce heterocycles, its importance extends to two other areas of organic synthesis, both of which are included in the current volume. First, the heteroatom-containing cycloadducts may be transformed into a variety of other functionalized organic molecules, whether cyclic or acyclic. Second, many 1,3-dipolar cycloadditions have the ability to generate rings (and the functionality derived from transformations of such rings) containing several contiguous stereocenters in one synthetic operation. The authors deal with relative stereocontrol in 1,3-dipolar cycloadditions in detail. Asymmetric versions of these dipolar cycloadditions represent an entirely new aspect of this new edition.<br>
