6969-36-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6969-36-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,6 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6969-36:
(6*6)+(5*9)+(4*6)+(3*9)+(2*3)+(1*6)=144
144 % 10 = 4
So 6969-36-4 is a valid CAS Registry Number.

Intramolecular Cycloadditions. Studies of Relative Asymmetric Induction

Harmata, Michael,Gamlath, Chandra B.,Barnes, Charles L.,Jones, Darin E.

, p. 5077 - 5092 (2007/10/02)

Treatment of both the E and Z isomers of alkoxyallylic sulfones 20a and 20b with TiCl4 results in the formation of 4 + 3 cycloadducts by intramolecular cycloaddition.The distribution of diastereomers is different from each isomer of educt.This suggests that cycloaddition occurs faster than any isomerization process of the intermediate allylic cations.Both the E and Z isomers of 20c lead to the same 4 + 3 cycloadduct with essentially complete diastereoselectivity.Inherently high simple diastereoselection and a strong conformational bias in the allylic cation intermediates for both isomers account for this selectivity.The importance of allylic cation stereochemistry in these reactions is underscored by the cyclization of 20d.The Z isomer give only 4 + 3 cycloadducts with excellent relative but poor simple diastereoselection, suggestive of a concerted reaction.The E isomer give a cycloadduct, enol ether 60, as the major cycloadduct as well as 4 + 3 cycloadducts and chloride-trapping product 61.This result is indicative of a stepwise reaction.The data reflect the importance of allylic cation stereochemistry in the regiochemical and stereochemical outcomes of intramolecular 4 + 2 cycloaddition reactions.
