权利人:JOHNSON & JOHNSON VISION CARE
摘要:The present invention provides indolinospiropyran compounds and methods for their manufacture, which compounds are useful as photochromic compounds. The compounds of the invention are substituted on the indole ring with succinimide, which substitution permits ring opening of the succinimide and modulation of the bulk and photochromic properties of the compounds. The compounds may be conveniently prepared using the solid phase organic synthesis of the invention.

摘要:A method for producing an optically active lactone compound by Baeyer-Villiger oxidation of a cyclic ketone compound with at least one kind of oxidants selected from the group consisting of hydrogen peroxide and urine-hydrogen peroxide adduct (UHP) using a cobalt(salen) complex having a cis-β structure expressed by the following formula (I) or (II) as a catalyst. n in which X and Y independently denote H, a t-butyl group or an electron-withdrawing substituting group and W is a halogen element. n in which X and Y independently denote H, a t-butyl group or an electron-withdrawing substituting group and Z − is a monovalent anion. The optically active lactone compounds can be used for the synthesis of medicines and argochemicals.
