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 using thiol-ene reaction and method for preparing the same, and composite of organic-inorganic materials comprising a cured product thereof and method for preparing the composite

The present invention relates to an epoxy compound having an alkoxysilylalkyl-S-alkyl group and a method for preparing the same, and a composite of organic-inorganic materials comprising a cured product thereof and a method for preparing the composite. Th

EPOXY COMPOUND HAVING ALKOXYSILYL GROUP, METHOD FOR PREPARING SAME, COMPOSITION COMPRISING SAME, CURED PRODUCT MADE THEREFROM, AND USE THEREOF

The present invention relates to an alkoxysilyl-based epoxy compound which exhibits excellent heat resistance characteristics, more particularly, a low coefficient of thermal expansion (CTE) and a high glass transition temperature in a composite, and/or which exhibits excellent flame retardancy in a cured product, and which eliminates the necessity of a separate silane coupling agent. The present invention also relates to a method for preparing the compound, and to a composition and cured product comprising the compound. According to the present invention, provided are: an alkoxysilyl-based epoxy compound having at least one alkoxysilyl group and at least two epoxy groups; a method for preparing the alkoxysilyl-based epoxy compound by means of the ring-opening of the epoxy of a starting material and alkoxysilylation; an epoxy composition comprising the epoxy compound; and a cured product made therefrom and the use thereof. The efficiency of the chemical bonding of the cured product, which is a composite of the composition comprising a novel alkoxysilyl-based epoxy compound according to the present invention, is improved when a composite is formed not only by chemical bonding between an alkoxysilyl group of the epoxy compound and a filler, but also by chemical bonding between alkoxysilyl groups of the epoxy compound having the alkoxysilyl groups. Accordingly, the compound of the present invention exhibits excellent heat resistance characteristics, such as a low CTE and a high glass transition temperature in a composite, and/or exhibits excellent flame retardancy in a cured product.
