We provide an account of synthetic strategies aimed at the efficient preparation of 4-amino-4-methyltetrahydro-2H-thiopyran 1,1-dioxide (3), an important cyclic sulfone building block for medicinal chemistry. A practical and scalable protocol has been developed that readily gives access to the title compound from commercially available and inexpensive starting materials. In addition, this novel approach has enabled the synthesis of various related 4,4-disubstituted cyclic sulfone derivatives that serve as valuable structural motifs for drug discovery.

The reaction of di(2-pyridyl) carbonate with a variety of alcohols including hindered secondary, tertiary and protected glycols afforded the corresponding mixed carbonate which was efficiently transformed into various carbamates in high yield under mild c
