Anti-Beckwith stereoselectivity in amidyl radical cyclisations: Bu 3SnH-mediated 5-exo-trig acyl mode cyclisation of 2-substituted pent-4-enamide radicals

2-Substituted amidyl radicals derived from 8a-d and 9a-d undergo acyl mode 5-exo-trig cyclisation to give 3,5-trans pyrrolidinones 11a-d and 14a-d as the major products in low diastereoselectivity (de = 9-36%). The steric nature of the nitrogen substituent attached to the amidyl radical does not have a significant effect on selectivity. The stereochemical outcome is opposite to that expected based upon applying the Beckwith rule.

Organoselenium-Induced Cyclization of Olefinic Imidates and Amides. Selective Synthesis of Lactams or Iminolactones

Lactams were formed selectively by the cyclization of olefinic imidates through the addition of a phenylseleno group to the double bond.Similar cyclization of olefinic amides, on the other hand, afforded either iminolactones or lactams depending on the st
