The disclosures herein provide compounds of formula I or its pharmaceutical acceptable salts, as well as polymorphs, enantiomers, stereoisomers, solvates, and hydrates thereof. These salts may be formulated as pharmaceutical compositions. The pharmaceutical compositions may be formulated for peroral administration- transdermal administration, transmucosal, syrups, topical, extended release, sustained release, or injection. Such compositions may foe used to treatment of vascular disorders or conditions such as thrombotic cerebrovascular or cardiovascular disease or its associated complications.
Visible-Light Photoredox-Catalyzed Giese Reaction: Decarboxylative Addition of Amino Acid Derived α-Amino Radicals to Electron-Deficient Olefins

A tin‐ and halide‐free, visible‐light photoredox‐catalyzed Giese reaction was developed. Primary and secondary α‐amino radicals were generated readily from aminoacids in the presence of catalytic amounts of an iridium photocatalyst. The reactivity of the α‐amino radicals has been evaluated for the functionalization of a variety of activated olefins.

catalyst. We already know that the aziridine ring is opened easily under the hydrogenation condition with any palladium catalysts, including Pd(II) or Pd(0). We thereby decided to reduce the reactivity by adding Lindlar catalyst. Lindlar catalyst consists of 5 wt % palladium supported on porous calcium carbonate with the treatment of various forms of lead and quinoline, i.e. a properly deactivated

A diarylethene compound reversibly convertible under photochromic and electrochromic conditions between a ring-open isomer of Formula (1A) and a ring-closed isomer of Formula (IB) wherein R5 is a substituted phenyl ring and Re is a substituted thiophene ring is provided. The photochromic-electrochromic diarylethene compound of Formula (1A)/(1B) have improved photochromic, electrochromic or photochromic and electrochromic properties, and is useful to provide variation of the light transmission properties of optical filters. The compound also possesses improved solubility making it suitable for incorporation in commercial products..

2′-bipyridine) is shown to be a versatile catalyst for a new photocatalytic Michael reaction. Under light irradiation in the presence of 2, a dithiane 2-carboxylic acid, obtained by simple hydrolysis of a commercially available ethyl ester, generates a 1,3-dithiane radical capable of performing addition to a variety of Michaelacceptors (e.g., unsaturated ketones, esters, amides and malonates). This broad
