✦ Synopsis

J1,,, = 1.4 Hz), 6.18 (H-2, B-part, J2,4 = 2 Ifz), 5.53 (H-3, d, J3,& and 2.78 (N-CH3, 5 ) . 13C(25.2 MHz. CDC13):6 154.5 (s), 150.6 ( 8 ) . 141.5 ( 8 ) . 138.9 (s), 136.2 (s), 135.6 (d), 134.2 (d), 128.6 (d), 127.6 (d), 127.4 (d), 88.7 (d), 62.0 (d), 57.0 (9). and 24.5 (9). The CH 0 assignments were in all cases made by comparison with the corresponding CD30-derivatives prepared by performing the interception in CD OD. 2.8 Hz), 4.60 (H-4, ddd). 3.45 (CH30, 5 ) 3 3 /20/ The 'H-NMR spectrum of the crude reaction mixture revealed only signals in accordance with the formation of four products a, m, likewise an CH 0-and an CH3N-group ( 6 3.30 ( 8 ) and 2.96 (s), respectively). Integration indicated a 4:5.5:1:5.3 mixture of &, &. and a. Similarly, 'H-NMR spectroscopy indicated that the reaction between & and MTAD in methanol led to the formation of products derived by interception of a corresponding intermediate. and u. The latter contained 3
