178421-76-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 178421-76-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,4,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 178421-76:
(8*1)+(7*7)+(6*8)+(5*4)+(4*2)+(3*1)+(2*7)+(1*6)=156
156 % 10 = 6
So 178421-76-6 is a valid CAS Registry Number.

Ready access to stereodefined β-hydroxy-γ-amino acids. Enantioselective synthesis of fully protected cyclohexylstatine

Castejon, Patricia,Moyano, Albert,Pericas, Miquel A.,Riera, Antoni

, p. 7063 - 7086 (1996)

A convenient entry to enantiopure syn or anti β-hydroxy-γ-amino acids is described. The starting compounds for the synthesis, anti 3-amino-1,2-diols, are readily available in high enantiomeric purity through catalytic asymmetric epoxidation of an allylic alcohol and titanium-promoted oxirane opening. After adequate protection of the nitrogen, a stereodivergent sequence leads to both anti and syn N-Boc aminoalkyl epoxides. Subsequent regioselective ring-opening with cyanide, protection of the resulting secondary alcohol and nitrile to carboxyl conversion afford, in good yields, protected β-hydroxy-γ-amino acid belonging to either the anti (erythro) or syn (threo) series. This methodology has been applied to the enantioselective preparation of cyclohexylstatine, a key component of several aspartyl protease inhibitors, in fully protected form.
