Synthesis of 2-TIPS-oxazol-5-ylboronic acid pinacol ester: efficient route to 5-(het)aryloxazoles via Suzuki cross-coupling reaction
摘要:
A facile synthetic route to the new 2-TIPS PS-oxazol-5-ylboronic acid pinacol ester was described herein. Its reactivity toward Suzuki cross-coupling reaction was studied to provide various 5-(het)aryloxazoles. A wide range of functions on the aryl moiety are tolerated. (C) 2009 Elsevier Ltd.

Modular symmetric ligands for selective recognition of cancer-relevant G-quadruplexes
in a symmetrical or asymmetrical way respectively, with the pendant groups pointing towards or away from the grooves. All bioxazole-based ligands showed anticancer activity in the low micromolar range. Particularly, the bioxazole derivative bearing piperazine groups was the most active compound of the investigated series, whereas the derivatives bearing morpholine groups were the most selective ones
