irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...

Organocatalytic asymmetric oxy-Michael addition to a γ-hydroxy-α,β-unsaturated thioester via hemiacetal intermediates.

We report an asymmetric oxy-Michael addition to a γ-hydroxy-α,β-unsaturated thioester via hemiacetal intermediates in the presence of Cinchona-alkaloid-thiourea-based bifunctional organocatalysts. This method provides a novel enantioselective route to β-hydroxy carboxyl compounds, which in turn can be used to synthesize valuable chiral building blocks.
