摘要：
A chiral tetraaminophosphonium salt represented by formula (1) and a method for producing chiral β-nitroalcohol comprising reacting an aldehyde or a ketone and a nitroalkane in the presence of the chiral tetraaminophosphonium salt represented by formula (1) and a base, or in the presence of a conjugated base of the chiral tetraaminophosphonium salt represented by formula (1): wherein R1 to R4 are independently a hydrogen atom or a monovalent hydrocarbon group; and, R1 and R2 are different groups or R3 and R4 are different groups.
