A facile access to chalcogen and dichalcogen bearing dialkylamines and diols
摘要:
A highly practical procedure for the preparation of novel classes of chalcogen bearing diamines [{H2N(CH2)n}E] and diols [{HO(CH2)n}(2)E] (n = 2 or 3 and E = Se or Te) by the reaction of disodiumchalcogenide and haloalkylamines or haloalcohols is presented.

Herein, we disclose the first set of unique selenium-containing SLAP (SiLicon Amine Protocol) reagents for the direct synthesis of C3/C5-substituted selenomorpholines and 1,4-selenazepanes from diverse (hetero)aldehydes under mild photocatalytic conditions. Enantiomerically pure 1,2-amino alcohol/α-amino acid versions of these heterocycles were also synthesized. Further, we have shown the late-stage
