All articles of this category In contrast to N -tosylsulfoximines, the relatively obscure N -nitrosulfoximines show good diastereoselectivity in alkylations and extraordinarily good leaving group properties in cyclizations via S N 2 displacement. Thus, methyl phenyl N -nitrosulfoximine serves as a chiral lynchpin for construction of chiral ring systems.
