Calculate Digit Verification of CAS Registry Number 586977-96:
(8*5)+(7*8)+(6*6)+(5*9)+(4*7)+(3*7)+(2*9)+(1*6)=250
250 % 10 = 0
So 586977-96-0 is a valid CAS Registry Number.

Cyclization into perhydronaphthalenones using samarium diiodide

Sono, Masakazu,Onishi, Sachiko,Tori, Motoo

, p. 3385 - 3395 (2007/10/03)

Samarium(II) diiodide has been employed to promote the intramolecular cyclization reactions of aldehydes or ketones onto α,β-unsaturated ketones. The cyclization reactions described herein provide a general approach to the syntheses of perhydronaphthalenones with a cis-relationship between the OH at C-5 and the proton or methyl group at C-4a with good diastereoselectivity under mild reaction conditions.
