immobilization of alcohols onto 2-chlorotritylchloride resin using microwaveirradiation was studied. Three different Fmoc-aminoalcohols were tested: the phenol-like Fmoc-tyramine, the primary alcohol Fmoc-ethanolamine, and the secondary alcohol Fmoc-4-hydroxypiperidine. Several reaction conditions were evaluated: different bases, reaction times, temperatures, and concentrations. Microwave immobilization
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

The total synthesis of the non-peptidefibrinogenreceptorantagonists, 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. Connection of a secondary alcohol to the DHP-resin, followed by iterative saponification and coupling sequences, provided novel drugs.
