Indoxylic acid esters as convenient intermediates towards indoxyl glycosides
Boettcher, Stephan,Thiem, Joachim
, p. 564 - 574 (2014/02/14)
Indoxylic acid methyl and allyl esters with varied halide-substitution patterns were obtained in excellent yields using a scalable route. Phase-transfer glycosylation of these key intermediates was carried out with various glycosyl halides. Subsequent mild silver-mediated decarboxylation followed by Zemplen deacetylation led to indoxyl glycosides in good overall yields. Indoxyl glycosides are well-established and widely used tools for enzyme screening and enzyme-activity monitoring. In the past, their synthesis has been difficult, so this new approach has led to a variety of useful structures. Indoxyl glycosides with varied halide-substitution patterns were synthesized using indoxylic acid esters as key intermediates. Glycosylation under phase-transfer conditions, ester cleavage, and mild decarboxylation led to the indoxyl glycosides in good yields. This approach enables access to a number of different indoxyl compounds. Copyright

In search for increased reactivity in strain-promoted azide alkyne cycloadditions (SPAAC), the synthesis of new and more reactive cyclooctynes is of pivotal importance. To identify cyclooctynes with enhanced reactivity, without loss of stability, the synthesis and kinetic analysis of new dibenzoazacyclooctyne (DIBAC) analogues were conducted. Starting from iodobenzyl alcohol analogues and ortho-ethynylaniline various substituted dihydrodibenzo[b,f]azocines were produced. Subsequent bromination and elimination proved to be difficult depending on the aromatic substitution pattern, yielding chloro-, bromo-, and methoxy-substituted DIBACs in moderate yield. In the elimination reaction towards nitro- and Br,Cl-DIBAC, the corresponding cyclooctene was obtained instead of the cyclooctyne. Additionally, a dimethoxy-substituted DIBAC analogue was prepared following an alternative route involving light-induced deprotection of a cyclopropenone derivative. In total, four DIBAC analogues were successfully prepared showing excellent rate constants in the SPAAC reaction ranging from 0.45 to 0.9 M-1 s -1, which makes them comparable to the fastest cyclooctynes currently known.
