β¦ Synopsis
Iodocyclization of the anti I-bromobenzyl ether acetate f=f is a key step in the first stereocontrolled
synthesis of the trisubstituted tetrahydrofuran davanone.

Carbenes generated from diazocompounds in the presence of palladium acetate add to vinylboronates, thus achieving an efficient highly stereoselective synthesis of functionalized cyclopropylboronates.
## Abstract The synthesis of spiro compounds through a MichaelβMichaelβaldol reaction is reported. The reaction affords spiropyrazolone derivatives in good yields, in almost diastereoβ and enantiopure form, and is catalyzed by diphenylprolinol derivatives. The reaction showed strong nonlinear effec
