Development of a Sila-Friedel−Crafts Reaction and Its Application to the Synthesis of Dibenzosilole Derivatives
摘要:
An intramolecular sila-Friedel-Crafts reaction was developed and applied to the synthesis of dibenzosilole derivatives. This reaction proceeds under mild conditions to afford the target in relatively high yield, indicating its availabilty as a versatile synthetic method. The synthesis of trisilasumanene, a silicon analogue of sumanene, was achieved using the present reaction.
