摘要

Abstract 5, 6-Dihydro-4-hydroxy-6, 6-dimethyl-2 H-thiopyrane-2-thione (1 I) and its tautomer 2-mercapto-4 H-thiopyrane-4-one (1 II) react with aliphatic aldehydes under different reaction conditions to yield mainly 5 R-7, 8-dihydro-2 H, 5 H, 6 H-thiopyrano [2, 3—b: 6, 5— b′]-bisthiopyran-4, 6 (3 H)-diones 2 and 2′ R, 4′ R-5, 6, 6′, 7′-tetrahydro-2-thioxo- spiro (4 H-thiopyran-3 (2 H), 3′(4′ H)-2′ H, 5′ H-thiopyrano-[2, 3—b]-thiopyran)-4, 5 ...
