Facile access to ring-fused aminals via direct α-amination of secondary amines with o-aminobenzaldehydes: Synthesis of vasicine, deoxyvasicine, deoxyvasicinone, mackinazolinone, and ruteacarpine

Secondary amines undergo redox-neutral reactions with aminobenzaldehydes under conventional and microwave heating to furnish polycyclic aminals via amine α-amination/N-alkylation. This unique α-functionalization reaction proceeds without the involvement of transition metals or other additives. The resulting aminal products are precursors for various quinazolinone alkaloids and their analogues. Georg Thieme Verlag Stuttgart. New York.
Natural (-)-vasicine as a novel source of optically pure 1-benzylpyrrolidin-3-ol
Aga, Mushtaq A.,Kumar, Brijesh,Rouf, Abdul,Shah, Bhahwal A.,Andotra, Samar S.,Taneja, Subhash C.

A facile and scalable methodology for the preparation of optically active (3S)-1-benzylpyrrolidin-3-ol (3), an important drug precursor, is reported. Starting from the naturally occurring alkaloid (-)-vasicine (1), a major alkaloid of the plant Adhatoda vasica, 3 was obtained in 84% overall yield (Scheme 3). Copyright
Reaction of deoxyvasicinone with organolithium compounds
Shakhidoyatov,Ibragimov,Mukhamedov
experimental part, p. 598 - 599 (2010/12/25)
4-Butyl-4-hydroxydeoxypeganine was prepared by lithiation of deoxyvasicinone. Deoxypeganine and 1,2-dihydrodeoxypeganine were produced by reduction of deoxyvasicinone with lithium aluminum hydride.
