Vergilius Redivivus: Studies in Joseph Addison's Latin Poetry

J.W. Binns, Modern Language Review 101.2 (2006), 504-5:
‘This book is an important contribution to the study of Anglo-Latin poetry in the late seventeenth and early eighteenth centuries … ’Haan provides an able and authoritative account …, setting the poems in their contexts, and providing for each a very clear and penetrating analysis which traces the classical well-springs that lie behind much of Addison’s Latin writing, and also calls attention to non-traditional elements’.

A novel structural class of photoswitchable oligonucleotide

Directed Michaelis–Arbuzov reactions of support-bound internucleotide O-benzyl- or O-methyl-phosphite triesters with meta-phenylazobenzylamine or alkane-/glycol-linked a,x-diamines were effected in the presence of iodine. The corresponding tritylated phosphoramidate-linked 11-mers were fully deprotected and released from the support under standard conditions and the fast- and slow-diastereoisomers of both the E- and the Z-meta-phenylazobenzyl-appended oligomers were readily resolved by RP-HPLC. The primary amine-functionalised oligonucleotides were either purified, detritylated and then finally treated with Nhydroxysuccinimidyl carboxylic acid ester derivatives of photoswitchable moieties (Route A) or first derivatised and then subsequently purified and detritylated (Route B). This latter route enabled resolution of fast- and slow-isomers of the trityl-on oligomers bearing novel photoswitchable azopyridine or 9-alkoxyanthracene moieties using RP-HPLC, following which the pure diastereoisomers were detritylated and characterised by MALDI-MS.
