Studies on the synthesis of quartromicins A3 and D3: Synthesis of the vertical and horizontal bis-spirotetronate fragments

Syntheses of the vertical (3) and horizontal (4) bis-spirotetronate units of quartromicins A3 and D3 are described, along with an efficient synthesis of α-hydroxy aldehyde exo-8b, a precursor to the exo-spirotetronate fragments 19 an

Synthesis of precursors of the agalacto (exo) fragment of the quartromicins via an auxiliary-controlled exo-selective Diels-Alder reaction

A direct synthesis of the α-hydroxyaldehyde exo-5, a precursor of the exo-spirotetronate subunit of the quartromicins, was achieved through an exo-selective Lewis acid-catalyzed Diels-Alder reaction of dienophile 12a and diene 1.

Diastereoselective synthesis of the endo- and exo-spirotetronate subunits of the quartromicins. The first enantioselective Diels-Alder reaction of an acyclic (Z)-1,3-diene.

[reaction: see text]. Diastereoselective syntheses of the endo- and exo-spirotetronates 1 and 2, corresponding to the galacto and agalacto fragments of quartromicins A3 and D3, are described. The key step of these syntheses are highly enantio- and diastereoselective Lewis acid catalyzed Diels-Alder reactions of the 1,1,3,4-tetrasubstituted diene 3.

Studies on the synthesis of the quartromicins: Partial stereochemical assignment of quartromicins A3 and D3 and diastereoselective synthesis of the endo- and exo-spirotetronate subunits

A partial stereochemical assignment of quartromicins A3 and D3 is presented, along with diastereoselective syntheses of the endo- and exo-spirotetronates 1 and 2, corresponding to the galacto and agalacto fragments of the proposed quartromicin stereostructure. The key steps of these syntheses are highly enantio- and diastereoselective Lewis acid catalyzed Diels-Alder reactions of 1,1,3,4-tetrasubstituted diene 24.
