76699-05-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76699-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76699-05:
(7*7)+(6*6)+(5*6)+(4*9)+(3*9)+(2*0)+(1*5)=183
183 % 10 = 3
So 76699-05-3 is a valid CAS Registry Number.

Stereospecific, R2AlCl-Promoted Intramolecular Ene Reaction of a 1,6-Dienoate: Evidence for a Concerted Mechanism

Oppolzer, Wolfgang,Mirza, Sohail

, p. 730 - 738 (1984)

Treatment of the 83percent-trans-13CH3-labelled 1,6-dienoate 7 with Et2AlCl at -78 deg C provided in high yield the ene product 9 containing 83percent 13C localized in the olefinic C(8)-methylene group.Accordingly, H-transfer occurs exclusively from the trans-methyl group of 7, consistent with a concerted ene process 7->9 thereby ruling out an intermediate cation 8 (Scheme 4).

High Acceleration and Improved Diastereoselectivity of Intramolecular Ene-Type Reactions by Diethylaluminum Chloride

Oppolzer, Wolfgang,Robbiani, Christian

, p. 2010 - 2014 (2007/10/02)

The pyrrolidines 2 and 10 were obtained by thermal ene-reactions at +70 deg and +180 deg from the (Z)-4-aza-1,6-diene 1 and from the (E)-4-aza-1,6-diene 9 in the ratios of 75:25 and 50:50, respectively.On the other hand, these cyclizations proceeded readily in the presence of diethylaluminum chloride at -78 deg and -35 deg giving in high yield the trans-pyrrolidine 2 from 1 with 100percent and from 9 with 89percent diastereoselectivity.

Synthetic studies in the α-kainic acid (2,3-trans,3,4-cis-2-carboxy- 4-isopropenylpyrrolidin-3-ylacetic acid) series

Kennewell, Peter D.,Matharu, Saroop S.,Taylor, John B.,Sammes, Peter G.

, p. 2542 - 2548 (2007/10/02)

The synthesis of (±)-cis- and (±)-trans-4- isopropenylpyrrolidin-3-ylacetic acids and the attempted synthesis of (±)-2,3-trans,3,4-cis-2-carboxy-4-isopropenylpyrrolidin-3-ylacetic acid, α-kainic acid, by intramolecular ene reactions are described. The ene cyclisation reaction has been shown to be kinetically controlled with the relative stabilities of the transition states controlling the product distribution. No isomerisation of starting diene or product pyrrolidine occurs under the conditions of the reaction.
