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...

Asymmetric Michael addition of α-fluoro-α-nitro esters to nitroolefins: towards synthesis of α-fluoro-α-substituted amino acids.

α-Fluoro-α-nitro esters were used as reaction partners in Michael addition to nitroalkenes, and the products were obtained in excellent chemical yields and with high enantioselectivities. Moreover, α-fluoro-α-amino ester with a quaternary α-carbon was prepared for the first time.

Organocatalytic asymmetric Michael-type reaction between β,γ-unsaturated α-keto ester and α-nitro ketone.

A Michael-type reaction of β,γ-unsaturated α-keto ester and α-nitro ketone was established. With a thiourea catalyst derived from cinchona alkaloid, the reactions afford products in 47-94% yields with 68-96% ee.
