91237-84-2 Usage
General Description
Boc-L-Pyroglutamic Acid Tert-Butyl Ester is a chemical compound used in organic synthesis and pharmaceutical research. It is a derivative of pyroglutamic acid, a naturally occurring amino acid found in various proteins and peptides. The compound is commonly employed as a building block for the synthesis of new drugs and pharmaceutical compounds due to its stability and ease of manipulation. Boc-L-Pyroglutamic Acid Tert-Butyl Ester is typically used as a protecting group to prevent unwanted reactions during chemical synthesis, and it can be deprotected to reveal the free amine group for further functionalization. Boc-L-PyroglutamicAcidTert-ButylEster plays a crucial role in the development of novel pharmaceuticals and bioactive compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 91237-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,3 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91237-84:
(7*9)+(6*1)+(5*2)+(4*3)+(3*7)+(2*8)+(1*4)=132
132 % 10 = 2
So 91237-84-2 is a valid CAS Registry Number.

Practical one-pot double functionalizations of proline
Huy, Peter,Schmalz, Hans-Guenther
body text, p. 954 - 960 (2011/05/07)
Solubilization of proline as the triethylammonium salt allows N-protection (as the Boc, Cbz or Moc derivative) and subsequent esterification or amidation of the carboxy terminus to be performed in an efficient one-pot fashion. Based on this concept, highly practical protocols were developed to prepare a series of proline derivatives (including Pro-Ser dipetides, Weinreb amides and N-protected proline esters), which are important intermediates, for instance, for the synthesis of proline-derived peptides, chiral reagents and catalysts for asymmetric synthesis.
