(Chemical Equation Presented) An efficient, stereospecific synthesis of the alkaloids senepodine G (2) and cermizine C (1) has been completed using the BF3·Et2O-promoted stereospecific addition of Me2CuLi to α,β-unsaturated lactam 6 to provide lactam 3, the addition of MeMgBr followed by HCl to convert 3 to senepodine G (2) (six steps, 40% overall yield), and the stereospecific NaBH4 reduction of 2 to give cermizine C (1) (seven steps, 40% overall yield).

This application discloses a novel process to synthesize (3-alkyl-5-piperidin-1-yl-3,3a-dihydro-pyrazolo[1,5-a]pyrimidin-7-yl)-amino derivatives, and intermediates useful in the synthesis thereof. The subject (3-alkyl-5-piperidin-1-yl-3,3a-dihydro-pyrazolo[1,5-a]pyrimidin-7-yl)-amino derivatives are useful as cyclin-dependent kinase inhibitor compounds (CDK inhibitors) in pharmaceutical preparations.
