565237-95-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 565237-95-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,5,2,3 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 565237-95:
(8*5)+(7*6)+(6*5)+(5*2)+(4*3)+(3*7)+(2*9)+(1*5)=178
178 % 10 = 8
So 565237-95-8 is a valid CAS Registry Number.

Asymmetric synthesis with 6-tert-butyl-5-methoxy-6-methyl-3,6-dihydro-2H-1,4-oxazin-2-one as a new chiral glycine equivalent: Preparation of enantiomerically pure α-tertiary and α-quaternary α-amino acids

Koch, Claus-Juergen,Simonyiova, Sona,Pabel, Joerg,Kaertner, Annerose,Polborn, Kurt,Wanner, Klaus Theodor

, p. 1244 - 1263 (2007/10/03)

The chiral oxazinone 2 has been developed as a new chiral glycine equivalent for the asymmetric synthesis of mono- and disubstituted α-amino acids. It is derived from the α-hydroxycarboxylic acid 1, which serves as a chiral auxiliary, and is easily accessible in enantiomerically pure form by optical resolution of the racemic compound (RS)-1. For alkylation reactions, 2 was deprotonated with sBuLi or phosphazenic base. Subsequent treatment with alkyl halides yielded the monosubstituted compounds 13/14a-c, e, f, (ent)-13d, (ent)-14d, while a second alkylation step, via the corresponding enolates, provided the disubstituted compounds 17/18a-d. Both alkylation steps proceeded with good yields and excellent diastereoselectivities (up to 99% de) and even less reactive electrophiles such as isopropyl iodide could be used. The results obtained in this reaction supported the assumption that the enolate of 2, as well as those of the monosubstituted derivatives of 2, have less tendency to form the aggregates that hamper alkylation reactions with other systems with higher oxygen content. From the major diastereomers of both the mono- and the disubstituted derivatives of 2 the corresponding α-amino acids 33a-c and 34a-d were obtained in high enantiomeric purity by hydrolytic cleavage of the oxazinone ring, accomplished either in two steps with aqueous TFA and aqueous NaOH or in one with either aqueous NaOH or 3 N HBr. Alkylation of the enolate ions of (S)-2 or (R)-2 with epichlorohydrins as bifunctional electrophiles provided the hydroxymethylenecyclopropyl derivatives 21 and 22. Hydrolysis of 21 and 22 afforded the free amino acids 35 and (ent)-35. Reductive amination with aniline after oxidation of 21 and 22 to the corresponding aldehydes 24 and 26 provided the compounds 25 and 27, whereas Mitsunobu treatment of 21 and 22 with 1-phenyl-3-(trifluoroacetyl)urea (28) afforded the urea derivatives 29 and 31. Hydrolysis of these compounds yielded the corresponding 1-aminocylopropanecarboxylic acid derivatives 36/(ent)-36 and (ent)-37. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.

Asymmetric synthesis employing a chiral 5-methoxy-1,4-oxazin-2-one derivative: Preparation of enantiomerically pure α-quaternary α-amino acids

Achatz, Oliver,Grandl, Andrea,Wanner, Klaus Theodor

, p. 1967 - 1978 (2007/10/03)

A new asymmetric synthesis of disubstituted α-amino acids is presented. This synthesis is based on the chiral 5-methoxy-1,4-oxazin-2-one derivative 5 relying on the α-hydroxy acid 1 as a chiral auxiliary. Alkylation reactions of the glycine equivalent 5 are performed by deprotonation with secbutyllithium and subsequent reaction with alkyl halides, yielding the monoalkylated compounds 13 and 14. A second alkylation step of the lithium enolates of 13 and 14 leads to the α,α-disubstituted compounds 17. Both steps proceed with good yields and excellent stereoselectivities (up to 99% de). From the major diastereomers 17c-d the corresponding α-amino acids 19c- d are obtained enantiomerically pure upon hydrolytic cleavage with aqueous sodium hydroxide. Alkylation of the enolate ion of 5 with epichlorohydrines as bifunctional electrophiles provides the cyclopropyl derivatives 20a-b. Direct hydrolysis or oxidation of 20a-b, followed by reductive amination and hydrolysis leads to the substituted 1-aminocyclopropanecarboxylic acids 21a- b and 24a-b.
