663619-22-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 663619-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,3,6,1 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 663619-22:
(8*6)+(7*6)+(6*3)+(5*6)+(4*1)+(3*9)+(2*2)+(1*2)=175
175 % 10 = 5
So 663619-22-5 is a valid CAS Registry Number.

Synthesis of Optically Pure Highly Functionalized γ-Lactams via 2-Azetidinone-Tethered Iminophosphoranes

Alcaide, Benito,Almendros, Pedro,Alonso, Jose M.

, p. 993 - 996 (2004)

A synthesis of optically pure densely functionalized γ-lactams starting from 2-azetidinone-tethered iminophosphoranes has been developed. Full chirality transfer has been accomplished from the enantiomerically pure 2-azetidinones. The addition of lithium acetylides to 4-oxoazetidine-2-carbaldehydes at -78 °C smoothly yielded propargylic alcohols with excellent diastereoselectivities. Propargylic alcohols were converted to mesylates, which by exposure to sodium azide afforded the corresponding azides. Treatment of β-lactams bearing an azido side chain with triphenylphosphine (TPP) gave λ5-phosphazenes (iminophosphoranes, phosphine imines), which were not isolated. The sodium methoxide promoted reaction of the phosphazene β-lactams smoothly provided γ-lactams, through a N1-C2 bond breakage process on the four-membered lactam with concomitant ring expansion, followed by hydrolysis.
