321309-76-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 321309-76-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,3,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 321309-76:
(8*3)+(7*2)+(6*1)+(5*3)+(4*0)+(3*9)+(2*7)+(1*6)=106
106 % 10 = 6
So 321309-76-6 is a valid CAS Registry Number.

Stereoselective synthesis of 5-(1-hydroxyalkyl)-2-pyrrolidinones utilizing oxidation of 5-alkylidene-2-pyrrolidinones to acyliminium ion precursors

Koseki, Yuji,Kusano, Shuichi,Ichi, Daisuke,Yoshida, Keiji,Nagasaka, Tatsuo

, p. 8855 - 8865 (2007/10/03)

A general method was devised for the LiN(TMS)2/AgOTf (=2:1)-catalyzed intramolecular (5-exo-dig) cyclization of β-alkynylamides 1 possessing alkyl, aryl or no functional groups at the terminal alkynes, to 5-alkylidene-2-pyrrolidinones 2. These 5-alkylidene-2-pyrrolidinones were oxidized to the diol-type alkoxylactams 3 by dimethyldioxirane (DMD) or mCPBA in MeOH. These alkoxylactams are useful as tertiary N-acyliminium ion precursors for the synthesis of threo-5-(1-hydroxyalkyl)-2-pyrrolidinone derivatives 5. (C) 2000 Elsevier Science Ltd.

Intramolecular cyclization of β-alkynylpropanamides to γ-alkylidene- γ-butyrolactams

Koseki,Kusano,Nagasaka

, p. 3517 - 3520 (2007/10/03)

A general method for the base-catalized intramolecular cyclization of β-alkynylpropanamides 1 to γ-alkylidene-γ-butyrolactames 2 (and 3) was established. Reactions of β-alkynylamides 1c-h, possessing alkyl groups at the terminal acetylenes, in the presence of a catalytic amount of LiN(TMS)2/AgOTf (= 2:1) in toluene gave exclusively (Z)-alkylidenelactames 2c-h in good yields.
