This work discloses a continuous flow carbonylation reaction using iron pentacarbonyl as source of CO. The described transformation using this surrogate was designed for use in commonly accessible flow equipment. Optimized conditions were applied to a sca

A highly enantioselective intramolecular 6-exo-trig aza-Michael addition was developed to afford chiral 3-substituted 1,2-oxazinanes in high yields (up to 99% yield) and good enantioselectivities (up to 98/2 er). These reactions were enabled by a quinine-derived primary-tertiary diamine as a catalyst and pentafluoropropionic acid (PFP) as a co-catalyst.

Mercuric acetate driven cyclization of γ-hydroxy-δ,ε-unsaturated urethanes 1a,b proceeded regio- and stereoselectively to afford cis-2-acetoxymercurymethyl-3-hydroxypyrrolidines 2a,b, respectively.These were transformed into the key intermediates for seve
