Organocatalytic annulation by functionalization of benzamide derivatives with alkynes has been developed. We report a new approach of cycloaddition under mild reaction conditions using simple catalysts, such as iodobenzene and peracetic acid, as oxidant. Those novel, mild reaction conditions provided a straightforward synthesis of isoquinolones with fast reaction rate. Notable selectivity in annulation of unsymmetrically

A flexible tube for an endoscope has a flexible tube substrate that is flexible and tubular and a resin layer (A) covering the flexible tube substrate. The resin layer (A) includes a thermoplastic resin (a) including at least one of a polyatnide resin, a polyurethane resin, a polyester resin, a polystyrene resin, or an acrylic resin and having a tensile strength at 10% elongation of 10 Pa or more and a hindered amine compound (b) having a molecular weight of 500 or more. Also provided are an endoscopic medical device including the flexible tube for an endoscope and a resin composition suitable for forming the resin layer of the flexible tube for an endoscope.
