Enantioselective total synthesis of 1-epi-pathylactone A

Autor: Imad Safir, Ramkrishna Basak, and Angèle Chiaroni, Angeline Chanu, Siméon Arseniyadis

Publikováno v: Organic letters. 9(7)

[structure: see text]. The first enantioselective total synthesis of 1-epi-pathylactone A, 3, has been accomplished using a PhI(OAc)2-mediated domino reaction as a key step. No diastereomeric separation was required throughout the whole synthetic sch

Synthesis of a norsesquiterpene spirolactone/steroidal hybrid by using an environmentally friendly domino reaction as a key step

Autor: Imad Safir, Angeline Chanu, Angèle Chiaroni, Siméon Arseniyadis, Ramkrishna Basak

European Journal of Organic Chemistry, Wiley-VCH Verlag, 2007, pp.4305-4312. ⟨10.1002/ejoc.200700446⟩

A new class of hybrid molecules is accessed by elaborating testosterone's AB ring into the norsesquiterpene spirolactone A′B′ ring. The cyclic ene-acetal 6b, obtained by a PhI(OAc)2-mediated domino process from vicinal unsaturated diol 5, is used

The bis-keto-hetero-IMDA option, with two ketone components (both the heterodiene and heterodienophile moieties) has been examined in several representative domino templates with the aim of ultimately developing efficient methods for the synthesis of
