Cascade Processes

Herein, we describe an efficient synthesis of C17α-OH-tigogenin, which is the aglycon of aspafiliosides E and F. The synthesis features three cascade processes, which involve the iodo-lactonization of furostan-26-acid, a cascade hydrolysis/intramolecular SN2 process, and a cascade intramolecular redox-ketalization process.

Cyclic Amines

A novel and efficient synthesis of tetrahydropyridine-, dihydropyrrole-, and tetrahydroazepine-3-carboxylates via cascade reactions of cyclic amines with CO and alcohols is presented. To our knowledge, this should be the first example in which functionalized N-heterocycles were prepared through Pd-catalyzed C(sp3)–H dehydrogenation and C(sp2)–H carbonylation of cyclic amines.
