Asymmetric functionalizations of α-sulfanyl cyclic ketones were realized via chiral phosphoric acid catalyzed enantioselective addition reactions with aldimines, azodicarboxylates and allenamides. A series of chiral organosulfur compounds possessing sulfur-containing tetrasubstituted stereocenters were accessed via these methods, with excellent regioselectivities and high stereoselectivities.

Vinylogous aza-Morita-Baylis-Hillman (aza-MBH) reactions of a vinylcyclopentenone with N -Boc imines provide the corresponding γ-adducts in high regioselectivity (10 examples). While the corresponding reactions with N -Ts imines give the α-adducts and γ-a
Direct enantioselective Mannich reactions of α-azido cyclic ketones: Asymmetric construction of chiral azides possessing an α-quaternary stereocenter
Ye, Xueqian,Pan, Yongkai,Yang, Xiaoyu
, p. 98 - 101 (2019/12/25)
Direct enantioselective Mannich reactions of α-azido cyclic ketones with aldimines are realized through chiral phosphoric acid catalysis, which generate chiral azides possessing an α-quanternary stereocenter with complete regioselectivities and high diast
