14369-81-4 Usage

Uses

Different sources of media describe the Uses of 14369-81-4 differently. You can refer to the following data:
1. Ethyl Buta-2,3-dienoate is a useful reactant for the synthesis of 9H-?pyrrolo[1,?2-?a]?indole derivatives via a phosphine-?promoted Michael addn.?/intramol. Wittig reaction.
2. Ethyl 2,3-butadienoate may be used in the synthesis of dihydropyrans by reacting with acyclic enones. It may also be used to synthesize spiranic heterocycles by reacting with heterocyclic bis-arylidene ketones via phosphine-catalyzed [3+2] annulations.

General Description

Ethyl 2,3-butadienoate is an α-allenic ester. The reaction of ethyl 2,3-butadienoate with N-tosylated imines in the presence of DABCO (1,4-diazabicyclo[2.2.2]octane) or DMAP (4-dimethylaminopyridine) forms azetidine derivatives or novel dihydropyridine derivatives respectively. The performance of bifunctional N-acyl aminophosphines to catalyze the asymmetric [3+2] cycloaddition of phenylidenemalononitrile with ethyl 2,3-butadienoate has been evaluated.

Check Digit Verification of cas no

The CAS Registry Mumber 14369-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,3,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14369-81:
(7*1)+(6*4)+(5*3)+(4*6)+(3*9)+(2*8)+(1*1)=114
114 % 10 = 4
So 14369-81-4 is a valid CAS Registry Number.

NHC-catalyzed [4 + 2] annulations of allenoates and 2,3-dioxopyrrolidine derivatives

Chen, Yangxu,Li, Tuanjie,Lu, Fangfang,Song, Xue,Yao, Changsheng,Yu, Chenxia,Zhang, Kai

supporting information, p. 1219 - 1225 (2022/02/21)

A facile NHC-catalyzed [2 + 4] annulation of allenoates with 2,3-dioxypyrrolidine derivatives was discovered, which paved a new avenue for the construction of highly substituted pyranopyrrole with moderate to good yields, high atom economy and mild reaction conditions. This journal is

Phosphine catalyzed [3+2] cyclization/Michael addition of allenoate with CS2to form 2-thineyl vinyl sulfide

Fei, Weihong,Xu, Ping,Hou, Jie,Yao, Weijun

supporting information, p. 11669 - 11672 (2020/10/19)

We have developed a DPPE-catalyzed three molecular two component tandem reaction of γ-substituted allenoate and CS2 to construct 2-thineyl vinyl sulfide through phosphine catalyzed [3+2] cyclization followed by Michael addition. The synthetic value of the

NHC-Catalyzed Aldol-Like Reactions of Allenoates with Isatins: Regiospecific Syntheses of γ-Functionalized Allenoates

Li, Sha,Tang, Ziwei,Wang, Yang,Wang, Dan,Wang, Zhanlin,Yu, Chenxia,Li, Tuanjie,Wei, Donghui,Yao, Changsheng

supporting information, p. 1306 - 1310 (2019/02/26)

An N-heterocyclic carbene (NHC) catalyzed γ-specific aldol-like reaction between allenoates and isatins has been achieved under mild conditions, giving trisubstituted allene derivatives bearing isatin moiety in moderate to good yields with high diastereoselectivity and excellent atom efficiency. The DFT computations indicated that the formation of the γ-adduct was more energetically favorable than that of the α-adduct. The result reported herein opens a new route for NHC-promoted allenoate-involved reaction.
