General Description

1-Ethynyl-4-tert-butyl-cyclohexan-1-ol is a chemical compound with the molecular formula C11H18O. It is a cyclohexan-1-ol derivative with a tert-butyl group and an ethynyl substituent attached to the cyclohexane ring. It is used in organic synthesis and pharmaceutical research as a building block for the synthesis of various compounds. The ethynyl group makes it suitable for use as a starting material for the synthesis of acetylenic compounds, which have a wide range of applications in medicinal chemistry and materials science. The tert-butyl group also provides steric hindrance, making the compound useful for controlling the reactivity and selectivity of reactions in which it is involved.

Check Digit Verification of cas no

The CAS Registry Mumber 20325-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,2 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20325-03:
(7*2)+(6*0)+(5*3)+(4*2)+(3*5)+(2*0)+(1*3)=55
55 % 10 = 5
So 20325-03-5 is a valid CAS Registry Number.

Base-Catalyzed Borylation/B-O Elimination of Propynols and B2pin2 Delivering Tetrasubstituted Alkenylboronates

Kuang, Zhijie,Chen, Haohua,Yan, Jianxiang,Yang, Kai,Lan, Yu,Song, Qiuling

supporting information, p. 5153 - 5157 (2018/09/12)

An efficient approach to tetrasubstituted alkenylboronates via a cascade borylation/B-O elimination of propynols and B2pin2 was disclosed. A series of tetrasubstituted alkenylboronates were readily furnished with this strategy in good yields, with further transformations leading to tetrasubstituted alkenes and β-diketones demonstrating the synthetic potential of the alkenylboronates constructed by this strategy as versatile intermediates in organic synthesis.

Catalytic dicyanative [4 + 2] cycloaddition triggered by cyanopalladation using ene-enynes and cyclic enynes with methyl acrylate

Arai, Shigeru,Koike, Yuka,Hada, Hirohiko,Nishida, Atsushi

supporting information; experimental part, p. 7573 - 7579 (2011/02/25)

Palladium-catalyzed dicyanative [4 + 2] cycloaddition using various ene-enynes was investigated. The key species in this process is a cyanoallene intermediate that is obtained by the cyanopalladation of conjugated enynes followed by 5-exo-cyclization. To

1-Chloroalkyl p-Tolyl Sulfoxides as Acetylide Anion Equivalent: A Novel Synthesis Including Asymmetric Synthesis of Propargylic Alcohols from Carbonyl Compounds

Satoh, Tsuyoshi,Hayashi, Yasumasa,Yamakawa, Koji

, p. 2153 - 2158 (2007/10/02)

Addition of the carbanion of 1-chloroalkyl p-tolyl sulfoxide to carbonyl compounds gave the adducts, which were heated in refluxing toluene or xylene to give vinyl chlorides in high overall yield.Dehydrochlorination of the vinyl chlorides with excess n-BuLi afforded propargylic alcohols in high yields.Asymmetric synthesis of both enantiomers of the propargylic alcohols was realized using optically active 1-chloroalkyl p-tolyl sulfoxide and aldehyde.
