This work reports a simple and efficient method for the direct phosphorylation of enamide under metal-free conditions. The P-centered radicals, derived from secondary phosphine oxides, are generated under mild reaction conditions in the presence of diphenyliodonium salt and Et3N and are introduced onto a range of enamides in good isolated yields. The method features broad substrate scope, good functional group tolerance, and efficient scale-up.
Conjugate additions of sulfur-stabilized anions to unsaturated lactams. Synthesis of polyfunctionalized benzo[a]quinolizinone systems

Conjugate addition reactions of sulfur-stabilized nucleophiles to the δ-lactam unit of tetrahydrobenzo[a]benzoquinolizines have been studied. The stereochemical outcome of the conjugate addition reaction depends on the nature of the substituent at the ang
Parham-type cyclization and nucleophilic addition-N-acyliminium ion cyclization sequences for the construction of the isoquinoline nucleus

Efficient methodologies based on the nucleophilic addition-N-acyliminium ion cyclization and the Parham-type cyclization sequences of N-phenethylimides 1 and 2 are reported for the synthesis of a dibenzo[a,h]quinolizidones, thiazolo-, oxazolo-, and imidazolo[4,3-a]isoquinolones.
