• organosilanes [2][7][8][9][10][11][12][13][14]. A number of efficient catalytic enantioselective methods has been developed for the synthesis of chiral organosilanes [15][16][17][18][19][20][21][22][23][24]. Out of the chiral organosilanes, nitrosilanes are important synthetic targets as they are precursors of

• nucleophiles to β-silyl α,β-unsaturated carbonyl compounds were documented as one of the straightforward and atom-economic approaches for the facile synthesis of chiral organosilanes (Scheme 1c–f) [30][31][32][33]. Recently, the aforementioned reaction under organocatalytic conditions has gained attention [34
