The first catalytic use of Ga(0) in organic synthesis has been developed by using a Ag(I) cocatalyst, crownether ligation, and ultrasonic activation. Ga(I)-catalyzed C-C bond formations between allyl or allenyl boronic esters and acetals, ketals, or aminals have proceeded in high yields with essentially complete regio- and chemoselectivity. NMR spectroscopic analyses have revealed novel transient Ga(I) catalytic species, formed in situ through partial oxidation of Ga(0) and B-Ga transmetalation, respectively. The possibility of asymmetric Ga(I) catalysis has been demonstrated.

1-Arylbut-3-en-1-ols react with trimethyl orthoformate in the presence of Lewis acids like InCl3, BiCl3, TiCl4, or BF3·OEt2 providing homoallyl ethers or homoallyl chlorides in high yields. Georg Thieme Verlag Stuttgart.

Systematic SAR studies on the thiazole ring 5-substituent of TCAT derivatives revealed that the introduction of a β-alkoxy or an amino group enhanced the inhibitory activity significantly. The present compounds are representative of specific Co(II)-MetAP1 inhibitors. Before the physiologically relevant metal ions for MetAPs are established, these small molecular compounds could be used as tools for detailed biological studies.
