Application In Synthesis of (3aR,8aR)-2,2-Dimethyl-4,4,6,8,8-pentaphenyltetrahydro-[1,3]dioxolo[4,5-e][1,3,2]dioxaphosphepine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (3aR,8aR)-2,2-Dimethyl-4,4,6,8,8-pentaphenyltetrahydro-[1,3]dioxolo[4,5-e][1,3,2]dioxaphosphepine, is researched, Molecular C37H33O4P, CAS is 147700-62-7, about Derivatives of α,α,α’,α’-tetraaryl-2,2-dimethyl-1,3-dioxolane-4,5-dimethanol (TADDOL) containing nitrogen, sulfur, and phosphorus atoms. New ligands and auxiliaries for enantioselective reactions. Author is Seebach, Dieter; Hayakawa, Michiya; Sakaki, Junichi; Schweizer, W. Bernd.

α,α,α’,α’-Tetraaryl-2,2-dimethyl-1,3-dioxolane-4,5-dimethanols I (R = Ph, 2-naphthyl, X = X’ = OH) are converted to bicyclic phosphites and phosphonites II (R1 = Me, Ph, OMe, OPh) by reaction with Cl2PR1. One or both OH groups of I (X = X’ = OH) can be replaced by Cl, and the halide in turn substituted by azide, thiocyanide, or sulfide (giving, e.g., III; X’ = S). Reduction of the azido group(s) to NH2 and N-alkylation or acylation furnishes a variety of amino alcs. I (X’ = NH2, NHMe, NMe2, NHCH2Ph, X = OH) and diamines I (X = X’ = NH2, NHMe, NMe2) as well as a bis(trifluoroacetamide) I (X = X’ = NHCOCF3). Cyclization of the aminoalc. I (X = OH, X’ = NH2) produces a bicyclic system III (X’ = NH), containing a pyrrolidine ring (structure determination by x-ray diffraction). The new chiral compounds containing nitrogen and phosphorus atoms might be useful ligands and auxiliaries for enantioselective syntheses.
