- Iron-catalyzed cross coupling of P-H/C-O bonds: Efficient synthesis of α-alkoxyphosphorus compounds
-
An efficient P-C bond-formation through iron-catalyzed cross coupling of P-H/C-O bonds is developed for the first time. This reaction proceeds efficiently to produce the corresponding valuable α-alkoxyphosphorus compounds under mild conditions with a wide generality.

- Total synthesis of (±)-kellermanoldione: stepwise cycloaddition of a functionalized diene and allenoate
-
Figur Presented The total synthesis of the diterpene kellermanoldione 1 is reported. Stepwise [4 + 2] cycloaddition of the ketal diene 8 and the allenoste 3 afforded the exo adduct 10x as the major product. It was converted into 1 via six steps, among them a key nonconjugative hydrolysis of a γ-methylene silyl enol ether

- DIALKYLAMINO GROUP TRANSFER FROM TITANIUM (IV) TO PHOSPHORYL CENTRE. STRUCTURE-REACTIVITY STUDIES
-
Reaction between phosphoryl substrates, (EtO)2P(O)X (X = H, R, OR) and dialkylaminoderivatives of Ti(IV), Ti(NR2)nCl4-n and Mn(NEt2)2 leads to the exchange of one or both EtO groups for the NR2 substituent.The reactivity of the system depends on electronic, as well as steric, effects of both substrates, and approximately correlates with the Lewis acid-base interaction between the substrates, as measured by the i.r. spectroscopy.
