(S)-Ethyl nipecotate D-tartrate

Check Digit Verification of cas no

The CAS Registry Mumber 163343-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,3,4 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163343-71:
(8*1)+(7*6)+(6*3)+(5*3)+(4*4)+(3*3)+(2*7)+(1*1)=123
123 % 10 = 3
So 163343-71-3 is a valid CAS Registry Number.

Synthetic method for (R)-N-tert-butoxycarbonyl-3-hydroxymethylpiperidine

-

, (2019/08/12)

The invention discloses a synthetic method for (R)-N-tert-butoxycarbonyl-3-hydroxymethylpiperidine. The method comprises the following four steps: synthesizing ethyl 3-piperidinecarboxylate (compoundII), synthesizing ethyl (R)-nipecotate-L-tartarate (compound III), synthesizing ethyl (R)-N-Boc-3-piperidinecarboxylate (compound IV) and synthesizing the (R)-N-tert-butoxycarbonyl-3-hydroxymethylpiperidine (compound V); and the method comprises the following special steps: synthesizing the compound II by using 3-piperidinecarboxylic acid (compound I) as a raw material through chloroacylation andethanol esterification; performing a salt formation reaction to form the compound III; adding a Boc anhydride and performing a reaction to obtain the compound IV; and finally performing sodium borohydride reduction to obtain the compound V. The method provided by the invention has the advantages of mild reaction conditions, environmental friendliness, simple operation steps, better reproducibilityand high practicability, and is suitable for industrial mass production of the (R)-N-tert-butoxycarbonyl-3-hydroxymethylpiperidine.
