Synthesis of α-Alkylidene-δ-valerolactones via the Conjugate Addition of Ketone Enolates to Functionalized Allyl Acetates
摘要:
Sequential addition of ketone enolates to allyl acetates bearing an ester, followed by reduction and cyclization provides a variety of substituted alpha-alkylidene-delta-valerolactones.

with a furan substituent at C-5 and a 4-methylindol-5-ylamino substituent at C-4, 1, was a potent inhibitor of PKCθ (IC50 = 4.5 nM). Replacement of the C-5 furan ring of 1 with bicyclic heteroaryl rings, led to compounds with significantly improved potency against PKCθ. Analog 6b with a 4-methylindol-5-ylamino group at C-4 and a 5-[(4-methylpiperazin-1-yl)methyl]-1-benzofuran-2-yl group at C-5 had an
