A two-carbon homologation of aldehydes and ketones was achieved by using a sequence involving the formation and the subsequent Pummerer-type ring fission of 5,6-dihydro-4H-1,3,4-thiadiazine rings possessing methylsulfinyl functionality at C-2.
通过使用涉及在 C-2 处具有甲基亚磺酰基官能团的 5,6-二氢-4H-1,3,4-噻二嗪环的形成和随后的普默勒型环裂变的序列,实现了醛和酮的双碳同系化。
