Development of the research lifecycle model for library services.

Question: Can the niche services of individual librarians across multiple libraries be developed into a suite of standard services available to all scientists that support the entire research lifecycle?

Setting: Services at a large, research-intensive state university campus are described.

Method: Initial data were collected via concept mapping by librarians. Additional data were collected at conferences and meetings through interactive poster presentations.

Diels-Alder cycloaddition of chiral nonracemic 2,5-diketopiperazine dienes.

Preparation of a chiral, nonracemic 2,5-diketopiperazine diene has enabled the investigation of intermolecular hetero-Diels-Alder cycloadditions. The diketopiperazine diene is reactive with both electron-rich and -deficient alkene substrates. Diastereofacial control in the cycloaddition is enforced with a removable aminal substituent.
