Tandem double-intramolecular [4+2]/[3+2] cycloadditions of nitroalkenes. Studies toward a total synthesis of daphnilactone B: Piperidine ring construction

Two model studies in support of a total synthesis of the complex polycyclic alkaloid daphnilactone B have been completed. The objectives of the models studies were to demonstrate the use of a tandem double-intramolecular [4+2]/[3+2] nitroalkene cycloaddit

Stereoselective Synthesis of Alcohols, XLII. Stereoselective Cyclization of (8-Oxo-2-octenyl)boronates to cis- or trans-Vinylcyclohexanol

Intramolecular allylboration reactions of (8-oxo-2-octenyl)boronates proceed with excellent diastereoselectivity: the E-isomer 1d leads to the trans-2-vinylcyclohexanol (2) with 99.5percent d.s., the corresponding Z-isomer 3d cyclizes to give the cis-isomer with a diastereoselectivity exceeding 99.8percent.Key Words: Cylization, stereoselective / Allylboration, intramolecular
