The formal synthesis of (±)-mersicarpine was achieved using an intermolecularradical addition−radical cyclization cascade. This key reaction represents a flexible, convergent route to numerous polycyclic indole derivatives.
Polymetallophilic organic compounds II. Organomagnesium intermediates of 2-alkyl-2-(chloromethyl)-1,3-dichloropropanes

The reactions of 2-ethyl- and 2-n-propyl-2-(chloromethyl)-1,3-dichloropropanes with magnesium in tetrahydrofuran were investigated. Hydrolysis of these Grignard reagents produced 2-ethyl-1-butene and 2-ethyl-1-pentene as the major product in the respective cases; carboxylation of the same organomagnesium compounds gave 4-ethyl- and 4-n-propyl-4-pentenoic acid, respectively. These products were consistent
Modulating the propeller-like shape of a tripodal C(CH2PPh2)3 fragment by the size of the substituent at the pivotal carbon atom in macrobicyclic tri-λ5-phosphazenes
The chiral macrobicyclic tri-λ5-phosphazenes formed by tripod–tripod coupling of tris(3-azidobenzyl)amines and 1,1,1-tris[(diphenylphosphino)methyl]methanes present helical topologies as a result of combining two propeller-shaped tripodal fragments with the same sense of twist.

The reaction of 1,1,1-tris(chloromethyl)propane with diphenylphosphine under phase-transfer conditions afforded 1,1,1-tris(diphenylphosphinomethyl)propane, whose oxidation gave a previously unknown representative of trigonal tris(phosphine oxides), viz., stable 1,1,1-tris(diphenylphosphorylmethyl)propane. Its analogs, viz., bis(diphenylphosphoryl)diphenylphosphinomethane and tris(diphenylphosphoryl)methane, are unstable in air and decompose with the cleavage of the P-C bond.
