CYANOMETHYLENETRIBUTYLPHOSPHORANE is a phosphorane reagent used in the asymmetric synthesis of fluorinated α-amino acids from alcohols, particularly in Mitsunobu–Tsunoda alkylation reactions with a chiral glycine equivalent. It facilitates the formation of high-yield, diastereoselective products when reacting with fluorinated alcohols and a nickel(II) glycine Schiff base complex. The reagent's role is critical in optimizing the reaction conditions for efficient synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 157141-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,4 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157141-27:
(8*1)+(7*5)+(6*7)+(5*1)+(4*4)+(3*1)+(2*2)+(1*7)=120
120 % 10 = 0
So 157141-27-0 is a valid CAS Registry Number.

Preparation of (cyanomethylene)tributylphosphorane: A new mitsunobu-type reagent

Sakamoto, Izumi,Nishii, Takeshi,Ozaki, Fumie,Kaku, Hiroto,Tanaka, Masami,Tsunoda, Tetsuto

, p. 1508 - 1509 (2005)

(Cyanomethylene)tributylphosphorane (CMBP), which promoted the alkylation of various nucleophiles (HA) with alcohols (ROH) to give RA (Mitsunobu-type reaction), was prepared in two steps starting from chloroacetonitrile.

A Convenient Method for the Asymmetric Synthesis of Fluorinated α-Amino Acids from Alcohols

Drouet, Fleur,Noisier, Anas F. M.,Harris, Craig S.,Furkert, Daniel P.,Brimble, Margaret A.

supporting information, p. 1195 - 1201 (2015/10/05)

Due to their numerous applications, fluorinated amino acids have recently attracted significant attention. The preparation of fluorine-containing phenylalanines, heteroaryl alanines and aliphatic fluorinated amino acids using Mitsunobu-Tsunoda alkylation of a chiral nucleophilic glycine equivalent with readily available alcohol substrates is described. The reaction proceeds in high yields and with excellent diastereoselectivity. This method provides an efficient synthetic route to fluorinated amino acids for which asymmetric approaches are scarce.

Novel reactivity of stabilized methylenetributylphosphorane: A new mitsunobu reagent

Tsunoda, Tetsuto,Ozaki, Fumie,Ito, Sho

, p. 5081 - 5082 (2007/10/02)

Cyanomethylenetributylphosphorane was shown to mediate the direct condensation of alcohols with O- and N-nucleophiles. A secondary alcohol, 2- octanol, reacted satisfactorily with Walden inversion of its carbinyl carbon.
