221493-47-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221493-47-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,4,9 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221493-47:
(8*2)+(7*2)+(6*1)+(5*4)+(4*9)+(3*3)+(2*4)+(1*7)=116
116 % 10 = 6
So 221493-47-6 is a valid CAS Registry Number.

Tuning stereoselection in Tethered Biginelli condensations. Synthesis of cis- or trans-1-oxo- and 1-iminohexahydropyrrolo[1,2-c]pyrimidines

McDonald, Andrew I.,Overman, Larry E.

, p. 1520 - 1528 (1999)

Stereoselection in tethered Biginelli condensations can be tuned to give either the cis or trans stereoisomer of 1-oxohexahydropyrrolo[1,2- c]pyrimidine and 1-iminohexahydropyrrolo[1,2-c]pyrimidine products (see eq 1). With substrates having urea and N-sulfonylguanidine functionality (Schemes 2 and 4), cis stereoselection (4-7:1) is observed when the condensation is accomplished under Knoevenagel conditions, while trans stereoselection (4-20:1) is observed when the condensation is carried out in the presence of polyphosphate ester (PPE). Under both conditions, steroselectivity is highest in the N-sulfonylguanidine series. With substrates bearing a basic guanidine unit, the trans product is formed exclusively under Knoevenagel conditions (Scheme 3).
