38197-43-2 Usage

General Description

2-Bromo-1-methoxy-3-methylbenzene, also referred to as 5-bromo-2-methylanisole, is a synthetic organic compound. As a derivative of anisole, it belongs to the class of aromatic compounds known as benzene and its derivatives. This chemical is identified with the CAS Registry Number 6071-25-6. In its pure form, it appears as a granular, crystalline powder or solid. It’s primarily used in the field of organic synthesis. As with many complex organic compounds, adequate safety measures should be taken in its handling and storage as the compound can be potentially hazardous.

Check Digit Verification of cas no

The CAS Registry Mumber 38197-43-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,1,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38197-43:
(7*3)+(6*8)+(5*1)+(4*9)+(3*7)+(2*4)+(1*3)=142
142 % 10 = 2
So 38197-43-2 is a valid CAS Registry Number.

Studies toward the Total Syntheses of Calyciphylline D-Type Daphniphyllum Alkaloids

Cui, Yi,Ren, Jun,Lv, Jiayuan,Wang, Zhongwen

supporting information, p. 9189 - 9193 (2021/11/30)

An efficient construction of an aza-[5.7.6.5] tetracyclic core structure of calyciphylline D-type Daphniphyllum alkaloids has been achieved. The synthetic route features a diastereoselective cyclopropanation, efficient construction of the core bridged 8-aza-[3.2.1]octane skeleton through a [3 + 2] IMCC strategy, oxidative dearomatization of phenol, and gram-scale preparation in each step.

1,2-asymmetric induction in diastereoselective zwitterionic aza-Claisen rearrangements: Key steps in optically active alkaloid synthesis

Heescher, Carolin,Schollmeyer, Dieter,Nubbemeyer, Udo

supporting information, p. 4399 - 4404 (2013/07/26)

The zwitterionic aza-Claisen rearrangement of optically active N-allylpyrrolidines and α-phenoxyacetyl fluorides proceeds with complete simple diastereoselectivity (internal asymmetric induction) and complete 1,2-asymmetric induction to generate a new C-C bond adjacent to a chiral C-N-Boc functionality. The resulting γ,δ-unsaturated amides were cyclised to give the corresponding pyrrolizidinones, which enabled the determination of the relative configuration of the stereotriads. Vinyl group degradation and a final lactam reduction gave an optically active analogue of (+)-petasinine (a pyrrolizidine alkaloid). Furthermore, the stereotriad-containing amides should be useful key intermediates for the total synthesis of optically active elaeocarpin (an indolizidine alkaloid). Copyright
