• : bicyclodihydrosilole; free radical; radical cascade reaction; SHi reaction; tris(trimethylsilyl)silane; Introduction Radical cyclization occupies a unique position in organic synthesis because it is a useful reaction for the construction of cyclic molecules [1][2][3][4][5][6][7][8][9][10]. The radical cascade

• similar cascade SHi reaction, because there were several reports so far that show such SHi reaction on silicon atoms progressing efficiently [23][24][25][26][27][28]. In this paper, we report a new synthesis of chiral bicyclodihydrosiloles through an addition–cyclization–SHi cascade reaction in one-pot
