899-79-6 Usage

Uses

As the provided materials do not specify the exact applications of 2-[(2E)-2-(6-methoxy-3,4-dihydronaphthalen-1(2H)-ylidene)ethyl]-2-methylcyclopentane-1,3-dione, it is not possible to list its uses based on the given information. However, given its structural complexity and resemblance to bioactive compounds, it may have potential applications in various industries such as pharmaceuticals, materials science, or chemical research. Further investigation and analysis are necessary to determine its specific uses and benefits in these fields.

Check Digit Verification of cas no

The CAS Registry Mumber 899-79-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,9 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 899-79:
(5*8)+(4*9)+(3*9)+(2*7)+(1*9)=126
126 % 10 = 6
So 899-79-6 is a valid CAS Registry Number.

Zn-Mediated Hydrodeoxygenation of Tertiary Alkyl Oxalates

Ye, Yang,Ma, Guobin,Yao, Ken,Gong, Hegui

supporting information, p. 1625 - 1628 (2021/01/18)

Herein we describe a general, mild, and scalable method for hydrodeoxygenation of readily accessible tertiary alkyl oxalates by Zn/silane under Ni-catalyzed conditions. The reduction method is suitable for an array of structural motifs derived from tertiary alcohols that bear diverse functional groups, including the synthesis of a key intermediate en route to estrone.

An asymmetric Torgov cyclization, catalyzed by a novel, highly Bronsted acidic dinitro-substituted disulfonimide, is described. The reaction delivers the Torgov diene and various analogues with excellent yields and enantioselectivity. This method was applied in a very short synthesis of (+)-estrone.
