(1R,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid is a chiral organic compound with the molecular formula C9H14O4. It features a cyclopentane ring with two methyl groups at the 1 and 2 positions and two carboxylic acid groups at the 1 and 3 positions. The compound exhibits a specific stereochemistry, with the R configuration at both the 1 and 3 positions, indicating that the hydroxyl groups are on the same side of the molecule when viewed from the direction of the substituents. This chirality is crucial for its potential applications in the synthesis of pharmaceuticals and other specialty chemicals, as the spatial arrangement of atoms can significantly influence its reactivity and biological activity.

595-32-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 595-32-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 595-32:
(5*5)+(4*9)+(3*5)+(2*3)+(1*2)=84
84 % 10 = 4
So 595-32-4 is a valid CAS Registry Number.

Modified McFadyen-Stevens reaction for a versatile synthesis of aliphatic/aromatic aldehydes: Design, optimization, and mechanistic investigations

The traditional McFadyen-Stevens reaction requires harsh alkaline reaction conditions, thus precluding application to the synthesis of aliphatic aldehydes. Our modified McFadyen-Stevens reaction enables the transformation from the N,N-acylsulfonyl hydrazine to the corresponding aldehyde upon treatment with an imidazole-TMS imidazole combination without relying on oxidative or reductive reagents. The reduced basicity and in situ protection of the resulting aldehyde widens the substrate scope to include aliphatic aldehydes, even ones bearing an α-hydrogen atom. Close examination of the side reactions for particular substrates in combination with theoretical considerations via DFT calculations led to a mechanistic understanding of the McFadyen-Stevens reaction involving an acyl diazene and a hydroxy carbene as reasonable intermediates.
