203070-87-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 203070-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,0,7 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 203070-87:
(8*2)+(7*0)+(6*3)+(5*0)+(4*7)+(3*0)+(2*8)+(1*7)=85
85 % 10 = 5
So 203070-87-5 is a valid CAS Registry Number.

Synthesis of 2,5-disubstituted 3-(phenylsulfonyl)pyrrolidines via 5-endo-trig cyclisation reactions

Craig, Donald,Jones, Philip S.,Rowlands, Gareth J.

, p. 1423 - 1425 (1997)

Reaction of lithiated (phenylsulfonyl)methane with enantiomerically pure N-diphenylphosphinylaziridines gives adducts 4, which may be acylated at the sulfone α-position by further lithiation and reaction with non-enolisable acid chlorides, giving ketones 5. Reduction followed by acetylation gives substrates 6, which undergo elimination and 5-endo-trig cyclisation to give 2,5-disubstituted 3-(phenylsulfonyl)pyrrolidines 7 in high yields and with excellent stereoselectivities. Some further reactions of the pyrrolidines are described.
