189328-24-3 Usage
Explanation
The compound is composed of 23 carbon atoms, 24 hydrogen atoms, and 5 oxygen atoms.
Explanation
The compound features a spiro[4.4]nonane ring system, which is a fused ring system consisting of two nonane rings connected at a single carbon atom, and a ketone functional group (C=O) present in the molecule.
Explanation
The compound exists in three different stereoisomeric forms, which are variations of the molecule with the same molecular formula but different spatial arrangements of the atoms.
Explanation
The (3R,4S,5R)isomer is one of the three stereoisomeric forms of the compound, characterized by the specific arrangement of the phenylmethoxy groups at the 3rd, 4th, and 5th carbon atoms of the spiro[4.4]nonane ring system.
Explanation
The compound has two phenylmethoxy groups (C6H5-O-CH3) attached to the 3rd and 4th carbon atoms of the spiro[4.4]nonane ring system, which contribute to its unique properties.
Explanation
As a complex organic molecule, it is expected that the compound would be soluble in common organic solvents such as dichloromethane, ethyl acetate, or acetone.
Explanation
The compound is likely stable under normal conditions, such as room temperature and atmospheric pressure, without undergoing significant decomposition or reaction.

Check Digit Verification of cas no
The CAS Registry Mumber 189328-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,2 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189328-24:
(8*1)+(7*8)+(6*9)+(5*3)+(4*2)+(3*8)+(2*2)+(1*4)=173
173 % 10 = 3
So 189328-24-3 is a valid CAS Registry Number.

A concise and efficient approach to the stereoselective total synthesis of (+)-secosyrin 1 and (+)-syributin 1
Sridhar, Perali Ramu,Rao, Boddu Umamaheswara
, p. 237 - 242 (2020/03/17)
A concise and stereoselective approach for the total synthesis of (+)-secosyrin 1 and (+)-syributin 1, metabolites of Pseudomonas syringae, is reported. The key synthetic step in this approach is a highly stereoselective construction of spiro center, through a one-pot dehydrohalogenation, intramolecular hetero-Michael addition (IHMA) and ester hydrolysis of halohydrins derived by the ring opening of 1,2-cyclopropanecarboxylated xylal derivative.
