The tethered aminohydroxylation of cyclic allylic carbamates is described using catalytic amounts of potassium osmate. The mechanism of reaction involves formation of an imido-osmium complex which adds intramolecularly to alkenes with complete control of

A new approach to the synthesis of carbamates based on a tin-catalyzed transcarbamoylation process has been developed. Reactions of primary and secondary alcohols with phenyl carbamate in toluene at 90 ° C proceed smoothly in the presence of tin-catalyst to generate the corresponding carbamates in good yields. This mild method exhibits a broad functional-group tolerance. Georg Thieme Verlag Stuttgart.

The first synthesis of the diterpene, 3-isocyano-3,7,11,15-tetramethylhexadeca-1,6,10,14-tetraene (geranyllinaloisocyanide, 1), has been achieved through an allyl cyanate-to-isocyanate rearrangement.The crucial step in this synthesis is in situ transformation of allyl isocyanates into stable allyl acetamides with trimethylaluminium.
