623571-19-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 623571-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,5,7 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 623571-19:
(8*6)+(7*2)+(6*3)+(5*5)+(4*7)+(3*1)+(2*1)+(1*9)=147
147 % 10 = 7
So 623571-19-7 is a valid CAS Registry Number.

Synthesis of the spermidine alkaloids (-)-(2R,3R)- and (-)-(2R,3S)-3-hydroxycelacinnine: Macrocyclization with oxirane-ring opening and inversion via cyclic sulfamidates

Khanjin, Nikolai A.,Hesse, Manfred

, p. 2028 - 2057 (2007/10/03)

The two epimers (-)-1a and (-)-1b of the macrocyclic lactama kaloid 3-hydroxycelacinnine with the (2R,3R) and (2R,3S) absolute configurations, respectively, were synthesized by an alternative route involving macrocyclization with the regio- and stereoselective oxirane-ring opening by the terminal amino group (Schemes 2 and 6). Properly N-protected chiral trans-oxirane precursors provided (2R,3R)-macrocycles after a one-pot deprotection-macrocyclization step under moderate dilution (0.005-0.01M). The best yields (65-85%) were achieved with trifluoroacetyl protection. Macrocyclization of the corresponding cis-oxiranes was unsuccessful for steric reasons. Inversion at OH-C(3) via nucleophilic displacement of the cyclic sulfamidate derivative with NaNO2 led to (2R,3S)-macrocycles. The synthesized (-)-(2R,3S)-3-hydroxycelacinnine ((-)-1b) was identical to the natural alkaloid.
