19028-69-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19028-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,2 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19028-69:
(7*1)+(6*9)+(5*0)+(4*2)+(3*8)+(2*6)+(1*9)=114
114 % 10 = 4
So 19028-69-4 is a valid CAS Registry Number.

Chemo- and Enantioselective Acyl Transfers by Lipases and Acylase I: Preparative Applications in Hydroxymethylpiperidine Chemistry

Lundell, Katri,Lehtinen, Petka,Kanerva, Liisa T.

, p. 790 - 796 (2007/10/03)

The lipase- and acylase I-catalysed acylation of bifunctional 2- and 3-hydroxymethylpiperidines (1 and 2) and the alcoholysis of the corresponding diacylated counterparts 7 and 8 have been studied. Lipase AK from Pseudomonas fluorescens allowed the preparative-scale resolution of 7 in neat butanol at 50% conversion whereas the 3-regioisomer 8 reacted with negligible enantioselectivity (E = 7). The lipase- and acylase I-catalysed acylations of 1 and 2 in organic solvents proceeded with low enantioselectivity. On the other hand, more than 90% of 1 and 2 were transformed to amino esters 3 and 4, respectively, in a highly chemoselective O-acylation with 2,2,2-trifluoroethyl butanoate in the presence of Candida antarctica lipase A in TBME. The O-protected product 3 in the reaction mixture was readily available to another transformation at the piperidine nitrogen although 3 was not separated due to intramolecular O→N acyl migration. The tendency for acyl migration was much less significant in the case of 4.
