9-Methoxystrobilurin K has been obtained from Favolaschia calocera. The previously proposed epoxyprenyl structure for 9-methoxystrobilurin K 2c and dioxan structure for 9-methoxystrobilurin L 3 have both been revised to the prenyldioxepin structure 1a. The epoxyprenyl structures of strobilurin D 2a and hydroxystrobilurin D 2c should also be revised.

The convergent stereocontrolled, asymmetric total synthesis of (+)-paraherquamide B is described. Key features of this synthesis include (1) an improved procedure to effect reduction of unprotected oxindoles to indoles; (2) a complex application of the So
SYNTHETIC STUDIES ON PARAHERQUAMIDE: SYNTHESIS OF THE 2H-1,5-BENZODIOXEPIN RING SYSTEM
Williams, Robert M.,Cushing, Timothy D.
, p. 6325 - 6328 (2007/10/02)
Various 2H-2,2-dimethyl-1,5-benzodioxepins have been synthesized en route to the oxindole moiety of paraherquamide (1).The key step is the 7-membered ring formation from prenylated catechols using either PhSeCl, N-PSP or m-CPBA/SnCl4.
