The 5'
49.	PURI, N, et al. (author) THE SYNTHESIS AND REACTIVITY OF NEW 2-(N,N-DIISOPROPYLAMINO)-3-METHYLSULFONYL-1,3,2-BENZOXAZAPHOSPHOLES - THE UTILITY OF THE 5-CHLORO ANALOG IN THE ONE-POT SYNTHESIS OF OLIGOTHIOPHOSPHATES - [AP(S)PPA, AP(S)PPPA, PPP5'A2'P(S)5'A, M(7)GP(S)PPA, AP(S)PPPP 1995 In: TETRAHEDRON. - : PERGAMON-ELSEVIER SCIENCE LTD. - 0040-4020. ; 51:10, s. 2991-3014 Journal article (other academic/artistic)abstract The synthesis of 2-(N,N-diisopropylamino)-2-3-dihydro-3-methylsulfonyl-1,3,2- benzoxazaphospholes 22, 23 and 24 is reported.
