An atom-economical diastereoselective synthesis of indenodithiepines and indenodithiocines has been developed via a domino reaction of propargylic alcohols and dithioacetals in the presence of InCl3 as a catalyst. A range of functionalized dithiepines and dithiocines, fused to the indene ring, were obtained in good to excellent yields under mild conditions.

We have developed catalytic allylation reactions of sulfonylimidates using allylic alcohols as allylating reagents. Stoichiometric amounts of neither activators nor bases are required in this reaction.

Although considerable work has been done on the formation of acetylmethylcarbinol by Aerobacter, except for the work of Koser (1918), O'Meara (1931), and Reynolds and Werkman (1937a,b), those studies employing cultures of growing cells were done in complex, chemically undefined media which tend to obscure the underlying chemical reaction. In the present study, intact, washed Aerobacter cells we...

The paper covers the principles and design aspects of cylindrical bins for the storage and reclaimation of bagasse. The system described (fig. 1) was originally designed and drawn up by the author in 1963 for the Mossman sugar mill. The design was not adopted, favour being given to the more conventional rectangular system with travelling suspended reclaimer. The first circular system, with a ca...
