A HOMOLOGATION OF ALDEHYDES AND KETONES VIA THE FORMATION AND THE SUBSEQUENT PUMMERER-TYPE RING FISSION OF 2-METHYLSULFINYL-5,6-DIHYDRO-4H-1,3,4-THIADIAZINE DERIVATIVES
K. Shimada et al., A HOMOLOGATION OF ALDEHYDES AND KETONES VIA THE FORMATION AND THE SUBSEQUENT PUMMERER-TYPE RING FISSION OF 2-METHYLSULFINYL-5,6-DIHYDRO-4H-1,3,4-THIADIAZINE DERIVATIVES, Chemistry Letters, (10), 1995, pp. 925-926
A two-carbon homologation of aldehydes and ketones was achieved by usi
ng a sequence involving the formation and the subsequent Pummerer-type
ring fission of 5,6-dihydro-4H-1,3,4-thiadiazine rings possessing met
hylsulfinyl functionality at C-2.
