Implication and improvement of stereoselective methylenation of a chiral aldehyde related to total synthesis of the furaquinocins

In relation to the total synthesis of the furaquinocins, stereoselective methylenation of chiral aldehyde 5 is described. The diastereoselectivity of epoxides 6a/b is high when stabilized sulfur ylides are employed. A double stereo-differentiation phenomenon was observed for the aminosulfoxonium ylide 8: the selectivity with (S)-8 was 30:1, while 5:1 with (R)-8.

Total synthesis of the furaquinocins

A viable synthetic route to the furaquinocin-class antibiotics is described. The key steps include (1) Co-complex mediated stereospecific 1,2- shift of an alkynyl group (9 → 6) to establish the c(2)-C(3) stereochemical relationship, (2) efficient construc
