Abstract

The previous racemic synthesis of a six-membered ring silane from tert-butyltrichlorosilane required six steps (22% overall yield). A considerably shortened reaction sequence now allows for its preparation from rarely used tert-butylsilane in only two steps (42% overall yield). The new access also offers more facile purification of the intermediate(s) and the target compound.

Key words

cyclization - Grignard reaction - hydrosilylation - nucleophilic substitution - silicon
