1, 1′-Dibenzyl-bis-(triazolyl)diphenylphosphine dioxide: a new efficient organocatalyst for silicon tetrachloride-mediated enantioselective Abramov-type phosphonylation of aldehydes with trialkyl phosphites
Abstract : Asymmetric phosphonylation of aldehydes with trialkyl phosphites mediated by SiCl4 and 1, 1′-dibenzyl-bis-(triazolyl)diphenylphosphine dioxide organocatalyst. Abstract : Asymmetric phosphonylation of aldehydes with trialkyl phosphites using a combination of SiCl4 and a novel 1, 1′-dibenzyl-bis-(triazolyl)diphenylphosphine dioxide organocatalyst has been developed. This protocol provides the corresponding α-hydroxyphosphonates with a broad range of functional groups and substitution patterns in excellent yields and good selectivities.
