## Abstract Alkylation of bicyclo[3.3.0]octaneโ2,8โdione (**1**), which is prepared by a modification of the procedure described in the literature, gives the methylโ and propynylโderivatives **6** and **7** (__Scheme 1__). In addition to the method described previously (__Scheme 2__), 9โmethylโ__ci
The present article reports our approach toward the synthesis of spiro compounds via indol-2,3-diones. Thus, reaction of indol-2,3-dione derivatives with a secondary cyclic amino acid, namely, (R)-(โซ-)ืโฌthiazolidine-4-carboxylic acid, affords a thiazolo-oxazolidinone as the main product. When the re
