experimental part, p. 2808 - 2811 (2011/06/19)
The immobilization of alcohols onto 2-chlorotritylchloride resin using microwave irradiation was studied. Three different Fmoc-aminoalcohols were tested: the phenol-like Fmoc-tyramine, the primary alcohol Fmoc-ethanolamine, and the secondary alcohol Fmoc-
Oligospiroketals as novel molecular rods

A modular approach for the synthesis of molecular rods based on oligospiroketals has been developed. The strategy relies on different terminal and intermediate segments, which are joined by ketal formation between ketones and diols. For this purpose it was necessary to develop a new ketalization method to circumvent some problems related with the established methods. The terminal segments are either derived from 4-piperidinone or from 4-oxocyclohexane carboxylic acid whereas the intermediate segments rest on pentaerythritol and cyclohexane-1,4-dione. A series of trispiro (14-18), hexaspiro (19) and nonaspiro (20) compounds have been prepared and characterized. From these we realized that it is imperative to use solubility enhancing groups if more than seven rings are joined.
Mio- and Dio-Fmoc - Two modified Fmoc protecting groups promoting solubility
Wessig, Pablo,Czapla, Sylvia,M?llnitz, Kristian,Schwarz, Jutta
, p. 2235 - 2238 (2007/10/03)
Two novel Fmoc-derived protecting groups, Mio-Fmoc and Dio-Fmoc, were developed, which cause dramatically enhanced solubility of the corresponding derivatives in most organic solvents. Furthermore, the suitability of these groups in solid-phase peptide synthesis was highlighted. Georg Thieme Verlag Stuttgart.
Concise synthesis of sibrafiban and lamifiban, two non-peptide fibrinogen receptor (GP IIb/IIIa) antagonists
Chang, Meng-Yang,Chen, Shui-Tein
, p. 133 - 135 (2007/10/03)
The total synthesis of the non-peptide fibrinogen receptor antagonists, sibrafiban (1) (Ro 48-3657) and lamifiban (2) (Ro 44-9883), is described. Both contain 4-hydroxypiperidine unit and the same solid-phase synthesis method was used as a key step. Conne
