444880-01-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 444880-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,8,8 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 444880-01:
(8*4)+(7*4)+(6*4)+(5*8)+(4*8)+(3*0)+(2*0)+(1*1)=157
157 % 10 = 7
So 444880-01-7 is a valid CAS Registry Number.

A novel tandem [4++2] cycloaddition-elimination reaction: 2-alkenyl-4,4-dimethyl-1,3-oxathianes as synthetic equivalents for α,β-unsaturated thioaldehydes

Ohsugi, Shin-Ichi,Nishide, Kiyoharu,Node, Manabu

, p. 1859 - 1871 (2007/10/03)

The first tandem cationic [4++2] polar cycloaddition-elimination reaction of 1-thia-1,3-butadienyl cations B with olefins to afford directly 3,4-dihydro-2H-thiopyrans D is described. The cations B were easily accessible by treatment of monothioacetals A, particularly the 2-alkenyl-4,4-dimethyl-1,3-oxathianes 1, with a hard Lewis acid. In this novel reaction, 2-alkenyl-4,4-dimethyl-1,3-oxathianes were utilized as synthetic equivalents for highly reactive α,β-unsaturated thioaldehydes. The effect of geminal dimethyl substituents on the oxathianes 1 and the mechanistic aspect of the reaction are considered. The reaction's asymmetric version was also investigated using a chiral oxathiane 4 derived from (-)-(1R,2R,5R)-2-(1-mercapto-1-methylethyl)-5-methylcyclohexanol. Although the enantioselectivities were moderate, the whole process can be done under odorless conditions.

1,3-oxathianes as perfuming and flavouring ingredients

-

Example 1, (2008/06/13)

The present invention relates to the perfumery and flavor industry. It concerns more particularly the use of a compound of formula (I) as perfuming or flavoring ingredient wherein R1 and R2 represent simultaneously or a independently a linear or branched alkyl or alkenyl group containing 1 to 4 carbon atoms, R3 represents a hydrogen, a cycloalkyl or a cycloalkenyl group, possibly substituted, a furanyl group, possibly substituted, a linear or branched alkyl or alkenyl group containing 1 to 12 carbon atoms, possibly substituted, or a linear or branched alkyl or alkenyl group containing 1 to 4 carbon atoms terminated by a carboxyl ester or amide group; and R4 represents a hydrogen or a linear alkyl group containing 1 to 4 carbon atoms. Substituents groups of R3 can be for example C1-C3 alkyl or alkenyl groups, an aromatic ring or C5-C7 cycloalkyl or cycloalkenyl groups, possibly substituted by methyl or ethyl groups.

A novel tandem [4++2] cycloaddition-elimination reaction of 4,4- dimethyl-2-styryl-1,3-oxathianes with olefins

Nishide, Kiyoharu,Ohsugi, Shin-Ichi,Node, Manabu

, p. 371 - 375 (2007/10/03)

A novel tandem [4++2] cycloaddition-elimination reaction of 1,3- oxathianes 1a, b with olefins promoted by titanium tetrachloride to give 3,4- dihydro-2H-thiopyrans 3 was developed. 4,4-Dimethyl-2-styryl-1,3-oxathiane (1a) was used as a synthet
