Synthesis of highly substituted oxetanes via [2+2] cycloaddition reactions of allenoates catalyzed by a guanidine Lewis base.

Chem. Commun. (Camb.) 49(28) , 2930-2, (2013)

The first synthesis of highly substituted 3-alkyl-oxetan-2-ylidenes from allenoates was developed by using the bicyclic guanidine 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as an exceptionally active n...

A selective intramolecular transacylation of taxoids accompanying with the oxetane ring opening.

Chem. Pharm. Bull. 60(3) , 415-8, (2012)

A selective intramolecular transacylation from C-4 to C-5 of taxoids, which occurred simultaneously with the oxetane D-ring opening and was promoted by TiCl4, was presented. The optimal condition was ...
