initiates cycloaromatization to form bond D.9 Application of this strategy allows efficient access to both the parent aglycon (3a) and the selectively protected derivative (3c) employed in the totalsynthesis reported herein. Overall, preparation of the enantioenriched furanose 6 and aglycon unit 3c and their conversion to 1 require only 11 synthetic operations with a longest linear sequence of seven steps

Ring expansion of dimethyl acetal 16 proceeds stereo- and regioselectively to 15 which is in turn converted to the desamidoanalogs of staurosporine, RK-286c, and TAN-1030a.

The first totalsynthesis of the natural product (+)-K252a (2) has been achieved in 12 steps from commercially available materials, with a longest linear sequence of seven steps and an overall yield of 21%. The synthetic strategy employs novel rhodium carbenoid chemistry in the construction of both the indolocarbazole aglycon (4) and the carbohydrate moiety (9).
