DOI: 10.1021/acs.orglett.2c01088
Abstract: B(C6F5)3 was found to catalyze an unusual double reduction of oxetanes by hydrosilane with aryl migration via neighboring group participation. Control experiments suggested that the phenonium ion serves as the key intermediate. Minor modification of… read more here.

DOI: 10.1039/d2ra01070d
Abstract: Spiro-heterocycles containing natural products and synthetic analogues have a broader biomedicinal application due to their rigid 3D conformation and structural implications. In this context, constructing spiro-isoxazoline systems have continued our interest in natural products and… read more here.
