The University of Alicante Library copy of Palmerin d'Oliva (London, 1637): A Bibliographical Description

The purpose of this article is to provide bibliographical information about a copy of the fourth edition of the two parts of Anthony Munday's translation of Palmerin d'Oliva (London, 1637; STC 19160) recently purchased by the University of Alicante Library and not mentioned in the standard bibliographies. The article contains a detailed bibliographical description based on Bowers's principles (1949) and is designed to be useful to scholars by making direct consultation of the copy in most cases unnecessary. The description is preceded by a short introduction to the literary text and its publication in England.

Synthesis of Chromen[4,3-b]pyrrolidines by Intramolecular 1,3-Dipolar Cycloadditions of Azomethine Ylides: An Experimental and Computational Assessment of the Origin of Stereocontrol

Azomethine ylides, generated from imine-derived O-cinnamyl or O-crotonyl salicylaldeyde and α-amino acids, undergo intramolecular 1,3-dipolar cycloaddition, leading to chromene[4,3-b]pyrrolidines. Two reaction conditions are used: (a) microwave-assisted heating (200 W, 185 °C) of a neat mixture of reagents, and (b) conventional heating (170 °C) in PEG-400 as solvent. In both cases, a mixture of two epimers at the α-position of the nitrogen atom in the pyrrolidine nucleus was formed through the less energetic endo-approach (B/C ring fusion). In many cases, the formation of the stereoisomer bearing a trans-arrangement into the B/C ring fusion was observed in high proportions. Comprehensive computational and kinetic simulation studies are detailed. An analysis of the stability of transient 1,3-dipoles, followed by an assessment of the intramolecular pathways and kinetics are also reported.
