Diels-Alder reactions of N-alkenyl-iminium salts: A novel route to indolizidine derivatives
Sheu,Smith,Matsumoto
, p. 253 - 262 (1993)
The Diels-Alder reaction of N-alkenyl-2-ethoxyiminium salts and simple alkenes gave Diels-Alder cycloadducts upon heating in nitromethane. Reduction of the intractable cycloadducts with hydride resulted in poor to moderate yields of indolizidine alkaloids.
N-VINYL-2-ETHOXYPYRROLIDINIMIUM TETRAFLUOBORATE: A NOVEL ENOPHILE AND SYNTHETIC EQUIVALENT FOR N-VINYLPYRROLIDINIMINIUM
Smith, Michael B.,Shroff, Hitesh N.
, p. 2229 - 2235 (2007/10/02)
Cycloaddition of N-vinyl-2-ethoxypyrrolidiniminium tetrafluoborate, 3, with alkenes, followed by hydride reduction, yields the 8-alkyloctahydroindolizines, 7 and 8 which would be derived from N-vinylpyrrolidiniminium, 2.This cycloaddition-reductive elimination sequence offers a new route to indolizidine type alkaloids.
