Facile synthesis of spirooxindole-pyrazolines and spirobenzofuranone-pyrazolines and their fungicidal activity.
Novel spirooxindole-pyrazolines and spirobenzofuranone-pyrazolines have been synthesized in good to excellent yields via the annulation reactions of the corresponding 3-alkylideneoxindoles and 3-alkylidenebenzofuranones with Huisgen zwitterions. The preliminary bioassay demonstrated that some of the spiropyrazolines possess good in vitro fungicidal activity against several crop fungi at a concentration of 50 μg mL(-1).

Chiral phosphine-catalyzed asymmetric allylic alkylation of 3-substituted benzofuran-2(3H)-ones or oxindoles with Morita-Baylis-Hillman carbonates.
An efficient chiral phosphine-catalyzed asymmetric substitution reaction of MBH carbonates with 3-substituted benzofuran-2(3H)-ones or 3-substituted oxindoles has been described in this context, giving the corresponding allylic alkylation products bearing adjacent quaternary and tertiary stereogenic centers in high yields, moderate diastereoselectivities and high enantioselectivities under mild conditions.

Diazonamide support studies: stereoselective formation of the C10 chiral center in both the CDEFG and AEFG fragments.
The synthesis of both the AEFG macrolactam and the CDEFG bis-indole/tyrosine units found in the marine natural product diazonamide A is presented. Key to the success of the synthesis is the highly stereoselective direct C-arylation of an oxindole by an aryllead(IV) reagent derived from tyrosine.
