Reactions of alcohols and silyl ethers in the presence of an indium/silicon-based catalyst system: deoxygenation and allyl substitution Akio Baba Abstract: An In(III)/Si catalyst system effects the direct allyl substitution of alcohols and silyl ethers under mild conditions. A deoxygenation of alcohols is also promoted by In[Cl.sub.3] catalyst. This method requires no pretreatment or protection […]

Greener and expeditious synthesis of bioactive heterocycles using microwave irradiation Vivek Polshettiwar Abstract: The utilization of green chemistry techniques is dramatically reducing chemical waste and reaction times as has recently been proven in several organic syntheses and chemical transformations. To illustrate these advantages in the synthesis of bioactive heterocycles, we have studied various environmentally benign […]
Use of sultines in the asymmetric synthesis of polypropionate antibiotics Pierre Vogel Laboratory of Glycochemistry and Asymmetric Synthesis (LGSA), Swiss Federal Institute of Technology (EPFL), Batochime, CH-1015 Lausanne, Switzerland Abstract: At low temperature and in the presence of an acid catalyst, S[O.sub.2] adds to 1,3-dienes equilibrating with the corresponding 3,6-dihydro-1,2-oxathiin-2-oxides (sultines). These compounds are unstable […]
