Beschreibung

Anwendung

1-Bromo-1-propene upon n-BuLi treatment generates the propynyllithium anion, in situ, which later undergoes nucleophilic addition reactions. Some of its other applications are:

• Synthesis of organic reagents such as methyl but-2-ynoate and 1-iodopropyne.
• Preparation o f intermediates in the total synthesis of (+)-aphanamol I and skyllamycins A-C.
• Synthesis of allylated pyrazoles, aryl alkynyl sulfides and allenamides.
