摘要:
Synthetic transformations of the 1-bicyclo[1.1.1]pentyl bridgehead radicals 11 generated from the corresponding bridgehead iodides 3 and carboxylic acids 5 are described. The relatively high nucleophilicity of these radicals was utilized in reactions with carbonyl compounds. In the reaction sequence of preparation of the iodides 3 and their further transformations, [1.1.1]propellane (2) is a synthetic equivalent of the recently described bicyclo[1.1.1]penta-1,3-dienyl dianion (8).
