摘要:
The invention relates to a new and efficient process for the preparation of a class of molecules, namely bicyclo[1.1.1]pentanes and derivatives thereof by reaction of [1.1.1]propellane with a variety of reagents under irradiation and/or in the presence of radical initiators to obtain bicyclo[1.1.1]pentanes asymmetrically substituted at position 1 and 3, which are useful as intermediates for the preparation of asymmetrically 1,3-disubstituted bicyclo[1.1.1]pentane derivatives and various physiologically active substances or materials containing these structures.
摘要:
A method of preparing a cyclopropane ring-bearing compound of the formula (I) in which R 1 and R 2 are independently selected from C 1 -C 10 alky], optionally substituted, or R 1 and R 2 together with the bonds linking them to the cyclopropane ring, form a monocyclic or bicyciic ring system, which may comprise at least one hetero-atom, comprising the reaction of a compound of formula (II) in which R 1 and R 2 have the significances hereinabove defined, with a compound of formula (III) in which X is selected a nucieofuge selected from halides and pseudohalides and Y is an electro flige selected from boranes and borates, in the presence of a metal catalyst complex selected from those that a useful for catalytic cyclopropanation and those useful for catalyzing Heck coupling. The method prov ides a particularly easy and non-hazardous method of cyclopropanation.
