Hj. Shi et al., Efficient one-pot synthesis of S-triazolo[3,4-b]-[1,3,5]thiadiazines containing a chiral side chain by double Mannich type reaction, J HETERO CH, 38(4), 2001, pp. 929-932
An efficient and convenience method has been developed via a one-pot double
Mannich type reaction for the synthesis of the important chiral s-triazole
derivatives: (S)-3-alpha -phenylethyl-2,4-dihydro-5-aryloxymethyl-1,2,4-tr
iazolo[3,4-b]-1,3,5-thiadiazines.
