A general synthetic strategy for the construction of branched triangulanes (BTs) (spirocondensed polycyclopropanes) has been elaborated. The synthetic utility of the method is illustrated by the synthesis of some members of the [5]- and [6]BT families, especially 13a,b and 14. An independent synthesis of the perspirocyclopropanated spiropentane 14 is also presented.
