Patent number: 5243064Abstract: The present invention relates to novel chromophore-containing compounds useful as sunscreen agents which have the ability to absorb both UVA and UVB wavelength radiation. These compounds comprise a specific type of UVA-absorbing chromophore covalently bonded to a specific type of UVB-absorbing chromophore. The chromophore moieties are covalently bonded together such that the electron systems of these moieties are directly coupled to thereby form a new chromophore.The present invention further relates to sunscreen compositions containing the hereinbefore described type of sunscreen agents. Furthermore, the present invention relates to methods for protecting the skin of humans or lower animals from the effects of UVA and UVB wavelength radiation. This method comprises topically applying to the skin an effective coating of a sunscreen composition of the present invention.Type: GrantFiled: July 31, 1992Date of Patent: September 7, 1993Assignee: The Procter & Gamble CompanyInventor: Anthony D. Sabatelli

Patent number: 5196607Abstract: A novel multi-step process for preparing the (4S)-enantiomer of 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone in a highly-optically pure form is disclosed. The process involves (1) first reacting 3,4-dichlorocinnamyl chloride with L-(-)-ephedrine in a chlorinated lower hydrocarbon solvent to form the corresponding chiral N-methyl-N-(.beta.-hydroxy-.beta.-phenylisopropyl)-3-(3,4-dichlorophenyl)p ropenoamide; (2) then subjecting the chiral .alpha.,.beta.-unsaturated amide formed in the first step to a Grignard reaction with phenyl magnesium chloride or bromide, followed by hydrolysis, to effect a conjugate addition of the phenyl group and the hydrogen element to the aforesaid .alpha.,.beta.-unsaturated propenoamide and so selectively form the corresponding chiral N-methyl-N-(.beta.-hydroxy-.beta.Type: GrantFiled: February 14, 1992Date of Patent: March 23, 1993Assignee: Pfizer Inc.Inventor: George J. Quallich
