1,6-Dioxaspiro[4.4]non-3-ene, 2-(2,4-hexadiynylidene)-, (Z)- is a complex organic chemical compound characterized by a unique molecular structure. It features a spiro ring system, which consists of a seven-membered ring with two oxygen atoms (1,6-dioxa) and a four-membered ring. The compound is further defined by a 2,4-hexadiynylidene group attached to the second carbon of the spiro system, with the (Z)-configuration indicating the geometric arrangement of the double bonds in the hexadiynylidene moiety. This specific arrangement of atoms and bonds gives the compound distinct chemical properties and potential applications in various fields, such as materials science and pharmaceuticals.

4575-53-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4575-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,7 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4575-53:
(6*4)+(5*5)+(4*7)+(3*5)+(2*5)+(1*3)=105
105 % 10 = 5
So 4575-53-5 is a valid CAS Registry Number.

A straightforward synthetic approach to the spiroketal-enol ethers synthesis of natural antifeeding compound tonghaosu and its analogs

Gao, Yang,Wu, Wen-Lian,Wu, Yu-Lin,Ye, Bin,Zhou, Rong

, p. 12523 - 12538 (2007/10/03)

Tonghaosu 1, a natural product discovered from several plants of tribe Athemdeae, is a [4.4]spiroketal with an enediyne side-chain and shows interesting insect antifeeding activity. In this paper a general and convenient synthetic methodology for the synthesis of 1, 2 and its spiroketal-enol ether derivatives is described. Thus, 3-(2'-furyl)-propan-1- ol 7a or 4-(2'-furyl)-butan-1-ol 7b prepared from furaldehyde was treated with n-butyl lithium and unsaturated aldehyde to provide the diol 5. Diol 5 could also be obtained from 5-(3-acetoxypropyl)-2-furaldehyde or 5-(4- acetoxybutyl)-2-furaldehyde and alkynyllithium. By careful treatment of 5 or 7 with acid, dehydration-cyclization occurred to give the desired spiroketal- enol ether in moderate to excellent yields.
