Calculate Digit Verification of CAS Registry Number 1423027-28:
(9*1)+(8*4)+(7*2)+(6*3)+(5*0)+(4*2)+(3*7)+(2*2)+(1*8)=114
114 % 10 = 4
So 1423027-28-4 is a valid CAS Registry Number.

Optically pure γ-butyrolactones and epoxy esters via two stereocentered HKR of 3-substituted epoxy esters: A formal synthesis of (-)-paroxetine, Ro 67-8867 and (+)-eldanolide

Devalankar, Dattatray A.,Karabal, Pratibha U.,Sudalai, Arumugam

, p. 1280 - 1285 (2013/05/08)

The HKR of racemic anti- or syn-3-substituted epoxy esters catalyzed by a Co(iii)salen complex provides ready access to the corresponding enantioenriched 3,4-disubstituted γ-butyrolactones and 3-substituted epoxy esters. This strategy has been successfully employed in the formal synthesis of biologically active 3,4-disubstituted piperidine derivatives, (-)-paroxetine and Ro 67-8867 and a natural product, (+)-eldanolide.
