1-Oxaspiro[4.5]decan-4-one is a cyclic ketone with a unique spiro structure, consisting of a seven-membered ring (decane) and a five-membered ring (oxaspiro). This organic compound is characterized by the presence of a carbonyl group (C=O) at the 1-position and a spiro junction between the two rings. It is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its structural complexity and potential for further functionalization. The compound is typically synthesized through multi-step reactions involving ring-closing metathesis or other advanced organic synthesis techniques. Its chemical properties include reactivity towards nucleophiles and electrophiles, making it a versatile building block for the development of complex molecular architectures.

22929-53-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22929-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,2 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22929-53:
(7*2)+(6*2)+(5*9)+(4*2)+(3*9)+(2*5)+(1*3)=119
119 % 10 = 9
So 22929-53-9 is a valid CAS Registry Number.

Strain-Promoted Oxidation of Methylenecyclopropane Derivatives using N-Hydroxyphthalimide and Molecular Oxygen in the Dark

Anderson, T. E.,Woerpel, K. A.

, (2020/07/30)

The hydroperoxidation of alkylidenecyclopropanes and other strained alkenes using an N-hydroxylamine and molecular oxygen occurred in the absence of catalyst, initiator, or light. The oxidation reaction proceeds through a radical pathway that is initiated by autoxidation of the alkene substrate. The hydroperoxides were converted to their corresponding alcohols and ketones under mild conditions.
