3209-39-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3209-39-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3209-39:
(6*3)+(5*2)+(4*0)+(3*9)+(2*3)+(1*9)=70
70 % 10 = 0
So 3209-39-0 is a valid CAS Registry Number.

Enantioselective Synthesis of γ-Hydroxynorvaline

Jacob,Roumestant,Viallefont,Martinez

, p. 691 - 692 (1997)

A new synthesis of enantiomerically pure γ-hydroxynorvaline is described. The key step involves diastereoselective alkylation of the chiral Schiff base 1 with primary iodo derivatives 2 easily prepared from propylene oxide.

Asymmetric Induction in Acyclic Radical Reactions: Enantioselective Syntheses of α-Amino Acids via Carbon-Carbon Bond Forming Radical Reactions.

Hamon, David P. G.,Massy-Westropp, Ralph A.,Razzino, Pasquale

, p. 4183 - 4194 (2007/10/02)

The derivative of glycine, 8-phenylmenthyl N-Boc-2-bromoglycinate 1 reacted with allyltri-n-butylstannanes via the corresponding radical 2 by the SH2' mechanism to give (2S) allyl amino acid derivatives with high diastereoselectivity.The reaction of 1 with triphenyl(1,2-propadienyl)stannane and triphenyl(2-propynyl)stannane gave the (2S) allenyl and (2S) propargyl amino acid derivatives respectively also with high diastereoselectivity but by a different mechanism.
