Modular Approach to Benzofurans, 2H-Chromenes and Benzoxepines via Claisen Rearrangement and Ring-Closing Metathesis: Access to Phenylpropanoids

Benzofurans, 2H-chromenes and benzoxepines are key structural elements present in several natural products and pharmaceuticals. Here, we describe an easy-to-execute strategy for the synthesis of benzofurans, 2H-chromenes and benzoxepines, by employing Claisen rearrangement and ring-closing metathesis as key steps. A variety of phenols were converted into useful oxacycles in good to excellent yields. The ring-closing metathesis approach has been used to produce phenylpropanoid natural products. Examples described here include, the naturally occurring benzofurans such as 7-methoxywutaifuranal, 7-methoxywutaifuranol, 7-methoxywutaifuranate and the O-prenylated natural products like boropinic acid, boropinols A and C.

EPOXY COMPOUND HAVING ALKOXYSILYL GROUP, METHOD FOR PREPARING SAME, COMPOSITION AND CURED MATERIAL COMPRISING SAME, AND USAGE THEREOF

Disclosed are an epoxy compound having an alkoxysilyl group, a composite of which exhibits good heat resistant properties and/or a cured product of which exhibits good flame retardant properties, a method of preparing the same, a composition comprising the same, a cured product of the composition and a use of the composition. An alkoxysilylated epoxy compound comprising at least one of Chemical Formula S1 substituent and at least two epoxy groups in a core, a method of preparing the epoxy compound by an allylation, a claisen rearrangement, a glycidylation and an alkoxysilylation, an epoxy composition comprising the epoxy compound, a cured product of the composition and a use of the composition are provided. The composite of the composition comprising the alkoxysilylated epoxy compound exhibits improved chemical bonding,-good heat resistant properties, a low CTE, a high glass transition temperature or Tg-less via the enhanced chemical bonding efficiency of alkoxysilyl group. The cured product of the composition exhibits good flame retardant properties.
