Abstract:
New lactone-containing photoacid generator compounds ("PAGs") and photoresist compositions that comprise such PAG compounds are provided. These photoresist compositions are useful in the manufacture of electronic devices
Abstract:
Compounds and compositions of said compounds along with methods of use of compounds are disclosed for treating ophthalmic conditions related to mislocalization of opsin proteins, the misfolding of mutant opsin proteins and the production of toxic visual cycle products that accumulate in the eye. Compounds and compositions useful in the these methods, either alone or in combination with other therapeutic agents, are also described.
Abstract:
A taxane derivative useful as an antitumor compound capable of oral administration is highly efficiently produced at low cost. An alkali metal permanganate is caused to act on a compound represented by the formula (1) (wherein R1 means alkyl, alkenyl, alkynyl, cycloalkyl, aryl, or a heterocyclic group and R2 means optionally protected hydroxy) to produce a compound represented by the formula (2), which is a raw material for an antitumor compound capable of oral administration.
