acid upon exposure to HCl and paraformaldehyde. This concisesecond-generation total synthesis of (+/-)-actinophyllic acid is realized in 22% overall yield from commercially available di-tert-butyl malonate and o-nitrophenylacetic acid by a sequence that proceeds by way of only six isolated intermediates. The first enantioselective total synthesis of (-)-actinophyllic acid (1) is accomplished by this

C=C bonds of enimines (α,β-unsaturated imines). Preliminary studies suggest their hydrolysed ring-open ω-amino enones are the likely substrates for this step. When combined with iminereductase (IRED)-mediated C=N reduction, the result is an efficient telescoped sequence for the preparation of diastereomerically enriched 2-substituted saturated amineheterocycles.
