4,4,6-Trimethyl-3,4-dihydropyrimidin-2(1H)-one is a heterocyclic organic compound with the molecular formula C7H12N2O. It features a pyrimidine ring structure, which is a six-membered aromatic ring containing four carbon atoms and two nitrogen atoms. The compound is characterized by the presence of three methyl groups (-CH3) attached to the pyrimidine ring, specifically at the 4, 4, and 6 positions. The numbering of the positions is based on the standard nomenclature for pyrimidines, where the 2(1H)-one indicates a hydrogen atom attached to the 2-position and an oxygen atom at the 1-position, forming a carbonyl group. 4,4,6-trimethyl-3,4-dihydropyrimidin-2(1H)-one is a dihydro derivative, meaning it contains one less double bond than the fully aromatic pyrimidine, resulting in a saturated ring structure. It is an important intermediate in the synthesis of various biologically active compounds and pharmaceuticals, such as certain antiviral and anticancer drugs, due to its unique chemical properties and reactivity.

4628-47-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4628-47-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4628-47:
(6*4)+(5*6)+(4*2)+(3*8)+(2*4)+(1*7)=101
101 % 10 = 1
So 4628-47-1 is a valid CAS Registry Number.

The Reactions of Monosubstituted Guanidins with α,β-Unsaturated Ketones

Wendelin, Winfried,Schermanz, Karl,Fuchsgruber, Alfred,Harler, Anton

, p. 1399 - 1412 (2007/10/02)

Action of methyl-, benzyl- and phenylguanidine on mesityloxide yields the 2-R3-imino-4,4,6-trimethyl-1,2,3,4-tetrahydropyrimidines resp. 2-R3-aminopyrimidines 8b, c and e, cyclohexylidenacetone reacts with benzylguanidine to give the 2-benzylimino-4-methyl-1,3-diazaspiroundeca-4-en resp. the benzylaminodiazaspiroundecadien (8d).The isomeric 1- and 3-R3-pyrimidinimines (resp. -amines) 9 b-e and 10 b-e are not formed in the reaction.The structures were proved by spectroscopical and chemical methods. - Keywords: Guanidines, monosubstituted; Ketone, α,β-unsatturated; Pyrimidines, 2-alkylimino-1,2,3,4-tetrahydro
