The syntheses of racemic thiazolidinyl thymine and cytosine derivatives 6a and 6b, and 10a and 10b, prototypes of a novel family of heterosubstituted nucleosides, have been achieved from rhodanine (3) or thiazolidine (7) by a short sequence of steps. The key reaction involved efficient coupling of silylated thymine and cytosine to N-Boc-protected 4- and 5- acetoxythiazolidines, 5 and 9, assisted by tert-butyldimethylsilyl trifluoro- methanesulfonate.

Organosulfides are a common class of structure units in bioactive molecules and functional materials motivating continuous developments of efficient synthetic methods. Herein, we report an electrophilic aryne-activated ring opening protocol of one or two

The reaction of lithiated N-Boc-thiazolidine and N-Boc-benzothiazolidine with benzophenone in the presence of (-)-sparteine afforded the products with up to 97% ee and 93% ee, respectively. The reaction with various aromatic and aliphatic aldehydes also afforded the products with high enantioselectivity and moderate diastereoselectivity. Each diastereomer could be converted to optically active diols. Consequently, lithiated N-Boc-thiazolidine and N-Boc-benzothiazolidine serve as chiral formyl anion equivalents. The reaction was confirmed to proceed through a dynamic thermodynamic resolution pathway.
